RHEL 6 : haproxy (RHSA-2013:0729)

Medium Nessus Plugin ID 119439

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

An updated haproxy package that fixes one security issue is now available for Red Hat OpenShift Enterprise 1.1.3.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

HAProxy provides high availability, load balancing, and proxying for TCP and HTTP-based applications.

A buffer overflow flaw was found in the way HAProxy handled pipelined HTTP requests. A remote attacker could send pipelined HTTP requests that would cause HAProxy to crash or, potentially, execute arbitrary code with the privileges of the user running HAProxy. This issue only affected systems using all of the following combined configuration options: HTTP keep alive enabled, HTTP keywords in TCP inspection rules, and request appending rules. (CVE-2013-1912)

In Red Hat OpenShift Enterprise, the HAProxy cartridge is added to your application when you select to have your application scaled. Due to the way this cartridge is currently used in Red Hat OpenShift Enterprise, the CVE-2013-1912 issue is not exploitable.

Red Hat would like to thank Willy Tarreau of HAProxy upstream for reporting this issue. Upstream acknowledges Yves Lafon from the W3C as the original reporter.

Users of Red Hat OpenShift Enterprise 1.1.3 are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Solution

Update the affected haproxy and / or haproxy-debuginfo packages.
