Synopsis

The remote CentOS host is missing a security update.

Description

An updated haproxy package that fixes one security issue is now available for Red Hat Enterprise Linux 6.

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)

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.

HAProxy is released as a Technology Preview in Red Hat Enterprise Linux 6. More information about Red Hat Technology Previews is available at https://access.redhat.com/support/offerings/techpreview/

All users of haproxy are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Solution

Update the affected haproxy package.
