Background ========== OpenSSL is an implementation of the Secure Socket Layer and Transport Layer Security protocols. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/openssl < 0.9.8e-r3 >= 0.9.8e-r3 Description =========== Moritz Jodeit reported an off-by-one error in the SSL_get_shared_ciphers() function, resulting from an incomplete fix of CVE-2006-3738. A flaw has also been reported in the BN_from_montgomery() function in crypto/bn/bn_mont.c when performing Montgomery multiplication. Impact ====== A remote attacker sending a specially crafted packet to an application relying on OpenSSL could possibly execute arbitrary code with the privileges of the user running the application. A local attacker could perform a side channel attack to retrieve the RSA private keys. Workaround ========== There is no known workaround at this time. Resolution ========== All OpenSSL users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8e-r3" References ========== [ 1 ] CVE-2006-3738 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3738 [ 2 ] CVE-2007-3108 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3108 [ 3 ] CVE-2007-5135 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5135 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200710-06.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
