TITLE

OpenSSL Montgomery Ladder implementation of the elliptic curve digital signature algorithm one-time token acquisition vulnerability

DESCRIPTION

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. OpenSSL is prone to an information-disclosure weakness. Attackers can exploit this issue to obtain sensitive information that may aid in launching further attacks. For HP IceWall products which bundle OpenSSL, an OpenSSL software update is available at the following location: http://www.hp.com/jp/icewall_patchaccess For RHEL, apply RHEL's OpenSSL patch: https://access.redhat.com/site/articles/904433 Note: CVE-2014-0076 is not impacted on RHEL https://access.redhat.com/security/cve/CVE-2014-0076 For HP-UX, apply HP-UX OpenSSL update as referenced in the following HP Security Bulletin HPSBUX03046 : https://h20564.www2.hp.com/portal/site/hpsc/public/kb/docDisplay/?docId=emr_n a-c04336637 HP recommends the following mitigation information to protect against potential risk for the following HP IceWall products. HP IceWall SSO Dfw and MCRP If possible, do not use SHOST setting which allows IceWall SSO Dfw or MCRP to use SSL/TLS for back-end web server connection. HP IceWall SSO Dfw Certd If possible, set LDAPSSL to 0 to make HP SSO IceWall Certd to not use SSL/TLS on any connection with LDAP server. Note: The HP IceWall product is only available in Japan. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Note: the current version of the following document is available here: https://h20564.www2.hp.com/portal/site/hpsc/public/kb/ docDisplay?docId=emr_na-c04336637 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c04336637 Version: 2 HPSBUX03046 SSRT101590 rev.2 - HP-UX Running OpenSSL, Remote Denial of Service (DoS), Code Execution, Security Restriction Bypass, Disclosure of Information, or Unauthorized Access NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.

Background ========== OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general purpose cryptography library. * The Montgomery ladder implementation of OpenSSL improperly handles swap operations (CVE-2014-0076). Workaround ========== Disabling the tls-heartbeat USE flag (enabled by default) provides a workaround for the CVE-2014-0160 issue. Resolution ========== All OpenSSL users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.1g" Note: All services using OpenSSL to provide TLS connections have to be restarted for the update to take effect. Utilities like app-admin/lib_users can aid in identifying programs using OpenSSL. As private keys may have been compromised using the Heartbleed attack, it is recommended to regenerate them.

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). 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). 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 ssl3_get_cert_verify function in s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman (DH) certificate without requiring a CertificateVerify message, which allows remote attackers to obtain access without knowledge of a private key via crafted TLS Handshake Protocol traffic to a server that recognizes a Certification Authority with DH support (CVE-2015-0205). 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 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-2014-0076) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 13.10: libssl1.0.0 1.0.1e-3ubuntu1.2 Ubuntu 12.10: libssl1.0.0 1.0.1c-3ubuntu2.7 Ubuntu 12.04 LTS: libssl1.0.0 1.0.1-4ubuntu5.12 After a standard system update you need to reboot your computer to make all the necessary changes. References: http://www.ubuntu.com/usn/usn-2165-1 CVE-2014-0076, CVE-2014-0160 Package Information: https://launchpad.net/ubuntu/+source/openssl/1.0.1e-3ubuntu1.2 https://launchpad.net/ubuntu/+source/openssl/1.0.1c-3ubuntu2.7 https://launchpad.net/ubuntu/+source/openssl/1.0.1-4ubuntu5.12 . The following Common Vulnerabilities and Exposures project ids identify them: CVE-2010-5298 A read buffer can be freed even when it still contains data that is used later on, leading to a use-after-free. CVE-2014-0076 ECDSA nonces can be recovered through the Yarom/Benger FLUSH+RELOAD cache side-channel attack. A third issue, with no CVE id, is the missing detection of the "critical" flag for the TSA extended key usage under certain cases. Additionally, this update checks for more services that might need to be restarted after upgrades of libssl, corrects the detection of apache2 and postgresql, and adds support for the 'libraries/restart-without-asking' debconf configuration. This allows services to be restarted on upgrade without prompting. The oldstable distribution (squeeze) is not affected by CVE-2010-5298 and it might be updated at a later time to address the remaining vulnerabilities. For the testing distribution (jessie), these problems will be fixed soon. OpenSSL Security Advisory [05 Jun 2014] ======================================== SSL/TLS MITM vulnerability (CVE-2014-0224) =========================================== An attacker using a carefully crafted handshake can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. This can be exploited by a Man-in-the-middle (MITM) attack where the attacker can decrypt and modify traffic from the attacked client and server. The attack can only be performed between a vulnerable client *and* server. OpenSSL clients are vulnerable in all versions of OpenSSL. Servers are only known to be vulnerable in OpenSSL 1.0.1 and 1.0.2-beta1. Users of OpenSSL servers earlier than 1.0.1 are advised to upgrade as a precaution. OpenSSL 0.9.8 SSL/TLS users (client and/or server) should upgrade to 0.9.8za. OpenSSL 1.0.0 SSL/TLS users (client and/or server) should upgrade to 1.0.0m. OpenSSL 1.0.1 SSL/TLS users (client and/or server) should upgrade to 1.0.1h. Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for discovering and researching this issue. This issue was reported to OpenSSL on 1st May 2014 via JPCERT/CC. The fix was developed by Stephen Henson of the OpenSSL core team partly based on an original patch from KIKUCHI Masashi. DTLS recursion flaw (CVE-2014-0221) ==================================== By sending an invalid DTLS handshake to an OpenSSL DTLS client the code can be made to recurse eventually crashing in a DoS attack. Only applications using OpenSSL as a DTLS client are affected. OpenSSL 0.9.8 DTLS users should upgrade to 0.9.8za OpenSSL 1.0.0 DTLS users should upgrade to 1.0.0m. OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1h. Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue. This issue was reported to OpenSSL on 9th May 2014. The fix was developed by Stephen Henson of the OpenSSL core team. DTLS invalid fragment vulnerability (CVE-2014-0195) ==================================================== A buffer overrun attack can be triggered by sending invalid DTLS fragments to an OpenSSL DTLS client or server. This is potentially exploitable to run arbitrary code on a vulnerable client or server. Only applications using OpenSSL as a DTLS client or server affected. OpenSSL 0.9.8 DTLS users should upgrade to 0.9.8za OpenSSL 1.0.0 DTLS users should upgrade to 1.0.0m. OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1h. Thanks to Jüri Aedla for reporting this issue. This issue was reported to OpenSSL on 23rd April 2014 via HP ZDI. The fix was developed by Stephen Henson of the OpenSSL core team. SSL_MODE_RELEASE_BUFFERS NULL pointer dereference (CVE-2014-0198) ================================================================= A flaw in the do_ssl3_write function can allow remote attackers to cause a denial of service via a NULL pointer dereference. This flaw only affects OpenSSL 1.0.0 and 1.0.1 where SSL_MODE_RELEASE_BUFFERS is enabled, which is not the default and not common. OpenSSL 1.0.0 users should upgrade to 1.0.0m. OpenSSL 1.0.1 users should upgrade to 1.0.1h. This issue was reported in public. The fix was developed by Matt Caswell of the OpenSSL development team. SSL_MODE_RELEASE_BUFFERS session injection or denial of service (CVE-2010-5298) =============================================================================== A race condition in the ssl3_read_bytes function can allow remote attackers to inject data across sessions or cause a denial of service. This flaw only affects multithreaded applications using OpenSSL 1.0.0 and 1.0.1, where SSL_MODE_RELEASE_BUFFERS is enabled, which is not the default and not common. OpenSSL 1.0.0 users should upgrade to 1.0.0m. OpenSSL 1.0.1 users should upgrade to 1.0.1h. This issue was reported in public. Anonymous ECDH denial of service (CVE-2014-3470) ================================================ OpenSSL TLS clients enabling anonymous ECDH ciphersuites are subject to a denial of service attack.
