Summary
Red Hat Security Advisory: openssl security update

Notes

Topic
An update for the OpenSSL component for JBoss Enterprise Web Server 1.0.2 for Solaris and Microsoft Windows that fixes multiple security issues is now available from the Red Hat Customer Portal. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Details
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. Multiple numeric conversion errors, leading to a buffer overflow, were found in the way OpenSSL parsed ASN.1 (Abstract Syntax Notation One) data from BIO (OpenSSL's I/O abstraction) inputs. Specially-crafted DER (Distinguished Encoding Rules) encoded data read from a file or other BIO input could cause an application using the OpenSSL library to crash or, potentially, execute arbitrary code. (CVE-2012-2110) A double free flaw was discovered in the policy checking code in OpenSSL. A remote attacker could use this flaw to crash an application that uses OpenSSL by providing an X.509 certificate that has specially-crafted policy extension data. (CVE-2011-4109) An information leak flaw was found in the SSL 3.0 protocol implementation in OpenSSL. Incorrect initialization of SSL record padding bytes could cause an SSL client or server to send a limited amount of possibly sensitive data to its SSL peer via the encrypted connection. (CVE-2011-4576) It was discovered that OpenSSL did not limit the number of TLS/SSL handshake restarts required to support Server Gated Cryptography. A remote attacker could use this flaw to make a TLS/SSL server using OpenSSL consume an excessive amount of CPU by continuously restarting the handshake. (CVE-2011-4619) This update also fixes additional security issues in OpenSSL that are not exposed in JBoss Enterprise Web Server: CVE-2011-4108, CVE-2012-0884, CVE-2012-1165, and CVE-2012-2333. Warning: Before applying the update, back up your existing JBoss Enterprise Web Server installation (including all applications and configuration files). All users of JBoss Enterprise Web Server 1.0.2 for Solaris and Microsoft Windows as provided from the Red Hat Customer Portal are advised to apply this update.
