TITLE

OpenSSL ‘ ssl3_get_key_exchange 'Function Encryption Vulnerability

DESCRIPTION

The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and trigger a loss of forward secrecy by omitting the ServerKeyExchange message. OpenSSL is prone to a security-bypass vulnerability. Successfully exploiting these issues may allow attackers to perform unauthorized actions. This may lead to other attacks.

The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack (CVE-2014-0076). The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug (CVE-2014-0160). The dtls1_reassemble_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a long non-initial fragment (CVE-2014-0195). The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition (CVE-2014-0198). OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the CCS Injection vulnerability (CVE-2014-0224). The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service (NULL pointer dereference and client crash) by triggering a NULL certificate value (CVE-2014-3470). The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the POODLE issue (CVE-2014-3566). The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 0.9.8zc, 1.0.0o, and 1.0.1j does not properly handle attempts to use unsupported protocols, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unexpected handshake, as demonstrated by an SSLv3 handshake to a no-ssl3 application with certain error handling. NOTE: this issue became relevant after the CVE-2014-3568 fix (CVE-2014-3569). The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c (CVE-2014-3570). OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not enforce certain constraints on certificate data, which allows remote attackers to defeat a fingerprint-based certificate-blacklist protection mechanism by including crafted data within a certificate&#039;s unsigned portion, related to crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and crypto/x509/x_all.c (CVE-2014-8275). NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated with servers or other TLS implementations (CVE-2015-0204). Use-after-free vulnerability in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import (CVE-2015-0209). The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse (CVE-2015-0287). The PKCS#7 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not properly handle a lack of outer ContentInfo, which allows attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, related to crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c (CVE-2015-0289). The updated packages have been upgraded to the 1.0.1m version where these security flaws has been fixed. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-5298 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0076 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0160 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0195 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0198 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0221 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0224 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3470 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3513 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3566 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3567 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3569 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3570 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3571 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3572 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8275 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0204 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0205 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0206 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0209 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0286 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0287 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0288 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0289 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0293 http://openssl.org/news/secadv_20150108.txt http://openssl.org/news/secadv_20150319.txt _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 324a85f7e1165ab02881e44dbddaf599 mbs2/x86_64/lib64openssl1.0.0-1.0.1m-1.mbs2.x86_64.rpm 9c0bfb6ebd43cb6d81872abf71b4f85f mbs2/x86_64/lib64openssl-devel-1.0.1m-1.mbs2.x86_64.rpm 58df54e72ca7270210c7d8dd23df402b mbs2/x86_64/lib64openssl-engines1.0.0-1.0.1m-1.mbs2.x86_64.rpm b5313ffb5baaa65aea05eb05486d309a mbs2/x86_64/lib64openssl-static-devel-1.0.1m-1.mbs2.x86_64.rpm a9890ce4c33630cb9e00f3b2910dd784 mbs2/x86_64/openssl-1.0.1m-1.mbs2.x86_64.rpm 521297a5fe26e2de0c1222d8d03382d1 mbs2/SRPMS/openssl-1.0.1m-1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.

(CVE-2014-3571) Karthikeyan Bhargavan discovered that OpenSSL incorrectly handled certain handshakes. (CVE-2014-3572) Antti Karjalainen, Tuomo Untinen and Konrad Kraszewski discovered that OpenSSL incorrectly handled certain certificate fingerprints. (CVE-2015-0204) Karthikeyan Bhargavan discovered that OpenSSL incorrectly handled client authentication. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10. This issue only affected Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2015-0206) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.10: libssl1.0.0 1.0.1f-1ubuntu9.1 Ubuntu 14.04 LTS: libssl1.0.0 1.0.1f-1ubuntu2.8 Ubuntu 12.04 LTS: libssl1.0.0 1.0.1-4ubuntu5.21 Ubuntu 10.04 LTS: libssl0.9.8 0.9.8k-7ubuntu8.23 After a standard system update you need to reboot your computer to make all the necessary changes. OpenSSL Security Advisory [08 Jan 2015] ======================================= DTLS segmentation fault in dtls1_get_record (CVE-2014-3571) =========================================================== Severity: Moderate A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. This issue affects all current OpenSSL versions: 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1k. OpenSSL 1.0.0 DTLS users should upgrade to 1.0.0p. OpenSSL 0.9.8 DTLS users should upgrade to 0.9.8zd. This issue was reported to OpenSSL on 22nd October 2014 by Markus Stenberg of Cisco Systems, Inc. The fix was developed by Stephen Henson of the OpenSSL core team. DTLS memory leak in dtls1_buffer_record (CVE-2015-0206) ======================================================= Severity: Moderate A memory leak can occur in the dtls1_buffer_record function under certain conditions. In particular this could occur if an attacker sent repeated DTLS records with the same sequence number but for the next epoch. The memory leak could be exploited by an attacker in a Denial of Service attack through memory exhaustion. This issue affects OpenSSL versions: 1.0.1 and 1.0.0. OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1k. OpenSSL 1.0.0 DTLS users should upgrade to 1.0.0p. This issue was reported to OpenSSL on 7th January 2015 by Chris Mueller who also provided an initial patch. Further analysis was performed by Matt Caswell of the OpenSSL development team, who also developed the final patch. no-ssl3 configuration sets method to NULL (CVE-2014-3569) ========================================================= Severity: Low When openssl is built with the no-ssl3 option and a SSL v3 ClientHello is received the ssl method would be set to NULL which could later result in a NULL pointer dereference. This issue affects all current OpenSSL versions: 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.1 users should upgrade to 1.0.1k. OpenSSL 1.0.0 users should upgrade to 1.0.0p. OpenSSL 0.9.8 users should upgrade to 0.9.8zd. This issue was reported to OpenSSL on 17th October 2014 by Frank Schmirler. The fix was developed by Kurt Roeckx. ECDHE silently downgrades to ECDH [Client] (CVE-2014-3572) ========================================================== Severity: Low An OpenSSL client will accept a handshake using an ephemeral ECDH ciphersuite using an ECDSA certificate if the server key exchange message is omitted. This effectively removes forward secrecy from the ciphersuite. This issue affects all current OpenSSL versions: 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.1 users should upgrade to 1.0.1k. OpenSSL 1.0.0 users should upgrade to 1.0.0p. OpenSSL 0.9.8 users should upgrade to 0.9.8zd. This issue was reported to OpenSSL on 22nd October 2014 by Karthikeyan Bhargavan of the PROSECCO team at INRIA. The fix was developed by Stephen Henson of the OpenSSL core team. RSA silently downgrades to EXPORT_RSA [Client] (CVE-2015-0204) ============================================================== Severity: Low An OpenSSL client will accept the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. A server could present a weak temporary key and downgrade the security of the session. This issue affects all current OpenSSL versions: 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.1 users should upgrade to 1.0.1k. OpenSSL 1.0.0 users should upgrade to 1.0.0p. OpenSSL 0.9.8 users should upgrade to 0.9.8zd. This issue was reported to OpenSSL on 22nd October 2014 by Karthikeyan Bhargavan of the PROSECCO team at INRIA. The fix was developed by Stephen Henson of the OpenSSL core team. DH client certificates accepted without verification [Server] (CVE-2015-0205) ============================================================================= Severity: Low An OpenSSL server will accept a DH certificate for client authentication without the certificate verify message. This effectively allows a client to authenticate without the use of a private key. This only affects servers which trust a client certificate authority which issues certificates containing DH keys: these are extremely rare and hardly ever encountered. This issue affects OpenSSL versions: 1.0.1 and 1.0.0. OpenSSL 1.0.1 users should upgrade to 1.0.1k. OpenSSL 1.0.0 users should upgrade to 1.0.0p. This issue was reported to OpenSSL on 22nd October 2014 by Karthikeyan Bhargavan of the PROSECCO team at INRIA. The fix was developed by Stephen Henson of the OpenSSL core team. Certificate fingerprints can be modified (CVE-2014-8275) ======================================================== Severity: Low OpenSSL accepts several non-DER-variations of certificate signature algorithm and signature encodings. OpenSSL also does not enforce a match between the signature algorithm between the signed and unsigned portions of the certificate. By modifying the contents of the signature algorithm or the encoding of the signature, it is possible to change the certificate's fingerprint. This does not allow an attacker to forge certificates, and does not affect certificate verification or OpenSSL servers/clients in any other way. It also does not affect common revocation mechanisms. Only custom applications that rely on the uniqueness of the fingerprint (e.g. certificate blacklists) may be affected. This issue affects all current OpenSSL versions: 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.1 users should upgrade to 1.0.1k. OpenSSL 1.0.0 users should upgrade to 1.0.0p. OpenSSL 0.9.8 users should upgrade to 0.9.8zd. One variant of this issue was discovered by Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS program and reported to OpenSSL on 1st December 2014 by NCSC-FI Vulnerability Co-ordination. Another variant was independently reported to OpenSSL on 12th December 2014 by Konrad Kraszewski from Google. Further analysis was conducted and fixes were developed by Stephen Henson of the OpenSSL core team. Bignum squaring may produce incorrect results (CVE-2014-3570) ============================================================= Severity: Low Bignum squaring (BN_sqr) may produce incorrect results on some platforms, including x86_64. This bug occurs at random with a very low probability, and is not known to be exploitable in any way, though its exact impact is difficult to determine. The following has been determined: *) The probability of BN_sqr producing an incorrect result at random is very low: 1/2^64 on the single affected 32-bit platform (MIPS) and 1/2^128 on affected 64-bit platforms. *) On most platforms, RSA follows a different code path and RSA operations are not affected at all. For the remaining platforms (e.g. OpenSSL built without assembly support), pre-existing countermeasures thwart bug attacks [1]. *) Static ECDH is theoretically affected: it is possible to construct elliptic curve points that would falsely appear to be on the given curve. However, there is no known computationally feasible way to construct such points with low order, and so the security of static ECDH private keys is believed to be unaffected. *) Other routines known to be theoretically affected are modular exponentiation, primality testing, DSA, RSA blinding, JPAKE and SRP. No exploits are known and straightforward bug attacks fail - either the attacker cannot control when the bug triggers, or no private key material is involved. This issue affects all current OpenSSL versions: 1.0.1, 1.0.0 and 0.9.8. OpenSSL 1.0.1 users should upgrade to 1.0.1k. OpenSSL 1.0.0 users should upgrade to 1.0.0p. OpenSSL 0.9.8 users should upgrade to 0.9.8zd. This issue was reported to OpenSSL on 2nd November 2014 by Pieter Wuille (Blockstream) who also suggested an initial fix. Further analysis was conducted by the OpenSSL development team and Adam Langley of Google. The final fix was developed by Andy Polyakov of the OpenSSL core team.

Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Datagram Transport Layer Security (DTLS) protocols, as well as a full-strength, general purpose cryptography library. A NULL pointer dereference flaw was found in the DTLS implementation of OpenSSL. A remote attacker could send a specially crafted DTLS message, which would cause an OpenSSL server to crash. A remote attacker could send multiple specially crafted DTLS messages to exhaust all available memory of a DTLS server. This flaw could possibly affect certain OpenSSL library functionality, such as RSA blinding. (CVE-2014-3570) It was discovered that OpenSSL would perform an ECDH key exchange with a non-ephemeral key even when the ephemeral ECDH cipher suite was selected. An attacker could use these flaws to modify an X.509 certificate to produce a certificate with a different fingerprint without invalidating its signature, and possibly bypass fingerprint-based blacklisting in applications. (CVE-2015-0205) All OpenSSL users are advised to upgrade to these updated packages, which contain a backported patch to mitigate the above issues. For the update to take effect, all services linked to the OpenSSL library (such as httpd and other SSL-enabled services) must be restarted or the system rebooted. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5.
