RHSA-2011:0677-01 -- Redhat openssl

ID: oval:org.secpod.oval:def:500175Date: (C)2012-01-31   (M)2017-09-22
Class: PATCHFamily: unix




OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. A buffer over-read flaw was discovered in the way OpenSSL parsed the Certificate Status Request TLS extensions in ClientHello TLS handshake messages. A remote attacker could possibly use this flaw to crash an SSL server using the affected OpenSSL functionality. This update fixes the following bugs: * The "openssl speed" command failed when openssl was running in FIPS mode, even if testing of FIPS approved algorithms was requested. FIPS mode disables ciphers and cryptographic hash algorithms that are not approved by the NIST standards. With this update, the "openssl speed" command no longer fails. * The "openssl pkcs12 -export" command failed to export a PKCS#12 file in FIPS mode. The default algorithm for encrypting a certificate in the PKCS#12 file was not FIPS approved and thus did not work. The command now uses a FIPS approved algorithm by default in FIPS mode. This update also adds the following enhancements: * The "openssl s_server" command, which previously accepted connections only over IPv4, now accepts connections over IPv6. * For the purpose of allowing certain maintenance commands to be run , an "OPENSSL_FIPS_NON_APPROVED_MD5_ALLOW" environment variable has been added. When a system is configured for FIPS mode and is in a maintenance state, this newly added environment variable can be set to allow software that requires the use of an MD5 cryptographic hash algorithm to be run, even though the hash algorithm is not approved by the FIPS-140-2 standard. Users of OpenSSL are advised to upgrade to these updated packages, which contain backported patches to resolve these issues and add these enhancements. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.
