TITLE

OpenSSL Denial of service vulnerability

DESCRIPTION

OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted DTLS message that is processed with a different read operation for the handshake header than for the handshake body, related to the dtls1_get_record function in d1_pkt.c and the ssl3_read_n function in s3_pkt.c. OpenSSL is prone to denial-of-service vulnerability due to a NULL pointer dereference condition. An attacker may exploit this issue to crash the application, resulting in denial-of-service conditions. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:062 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : openssl Date : March 27, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been discovered and corrected in openssl: Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment (CVE-2010-5298). 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). 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 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). 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). 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 (CVE-2014-3572). 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). 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 RSA-to-EXPORT_RSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to the FREAK issue. 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). 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.

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 could lead to a Denial Of Service attack. 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.
