Synopsis

Moderate: openssl security update

Type/Severity

Security Advisory Moderate

Topic

An update for the OpenSSL component for JBoss Enterprise Application Platform 5.2.0 for Solaris and Microsoft Windows that fixes two security issues is now available from the Red Hat Customer Portal.

The Red Hat Security Response Team has rated this update as having moderate 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.

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.

A NULL pointer dereference flaw was found in the OCSP response verification in OpenSSL. A malicious OCSP server could use this flaw to crash applications performing OCSP verification by sending a specially-crafted response. (CVE-2013-0166)

It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2013-0169)

Warning: Before applying this update, back up your existing JBoss Enterprise Application Platform installation (including all applications and configuration files).

All users of JBoss Enterprise Application Platform 5.2.0 for Solaris and Microsoft Windows as provided from the Red Hat Customer Portal are advised to apply this update.
