-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: openssl security update Advisory ID: RHSA-2012:1307-01 Product: JBoss Enterprise Application Platform Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1307.html Issue date: 2012-09-24 CVE Names: CVE-2011-4108 CVE-2011-4109 CVE-2011-4576 CVE-2011-4619 CVE-2012-0884 CVE-2012-1165 CVE-2012-2110 CVE-2012-2333 ===================================================================== 1. Summary: An update for the OpenSSL component for JBoss Enterprise Application Platform 5.1.2 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. 2. Description: 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 Application Platform: CVE-2011-4108, CVE-2012-0884, CVE-2012-1165, and CVE-2012-2333. Warning: Before applying this update, back up your JBoss Enterprise Application Platform's "server/[PROFILE]/deploy/" directory, along with all other customized configuration files. All users of JBoss Enterprise Application Platform 5.1.2 for Solaris and Microsoft Windows as provided from the Red Hat Customer Portal are advised to apply this update. 3. Solution: The References section of this erratum contains a download link (you must log in to download the update). Before applying the update, back up your existing JBoss Enterprise Application Platform installation (including all applications and configuration files). JBoss server instances configured to use the Tomcat Native library must be restarted for this update to take effect. 4.
