Synopsis: Moderate: openssl security update Advisory ID: SLSA-2014:1052-1 Issue Date: 2014-08-13 CVE Numbers: CVE-2014-3508 CVE-2014-3505 CVE-2014-3506 CVE-2014-3510 CVE-2014-3509 CVE-2014-3507 CVE-2014-3511 -- A race condition was found in the way OpenSSL handled ServerHello messages with an included Supported EC Point Format extension. A malicious server could possibly use this flaw to cause a multi-threaded TLS/SSL client using OpenSSL to write into freed memory, causing the client to crash or execute arbitrary code. (CVE-2014-3509) It was discovered that the OBJ_obj2txt() function could fail to properly NUL-terminate its output. This could possibly cause an application using OpenSSL functions to format fields of X.509 certificates to disclose portions of its memory. (CVE-2014-3508) A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions. (CVE-2014-3511) Multiple flaws were discovered in the way OpenSSL handled DTLS packets. A remote attacker could use these flaws to cause a DTLS server or client using OpenSSL to crash or use excessive amounts of memory. (CVE-2014-3505, CVE-2014-3506, CVE-2014-3507) A NULL pointer dereference flaw was found in the way OpenSSL performed a handshake when using the anonymous Diffie-Hellman (DH) key exchange. A malicious server could cause a DTLS client using OpenSSL to crash if that client had anonymous DH cipher suites enabled. (CVE-2014-3510) 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. -- SL6 x86_64 openssl-1.0.1e-16.el6_5.15.i686.rpm openssl-1.0.1e-16.el6_5.15.x86_64.rpm openssl-debuginfo-1.0.1e-16.el6_5.15.i686.rpm openssl-debuginfo-1.0.1e-16.el6_5.15.x86_64.rpm openssl-devel-1.0.1e-16.el6_5.15.i686.rpm openssl-devel-1.0.1e-16.el6_5.15.x86_64.rpm openssl-perl-1.0.1e-16.el6_5.15.x86_64.rpm openssl-static-1.0.1e-16.el6_5.15.x86_64.rpm i386 openssl-1.0.1e-16.el6_5.15.i686.rpm openssl-debuginfo-1.0.1e-16.el6_5.15.i686.rpm openssl-devel-1.0.1e-16.el6_5.15.i686.rpm openssl-perl-1.0.1e-16.el6_5.15.i686.rpm openssl-static-1.0.1e-16.el6_5.15.i686.rpm - Scientific Linux Development Team
