RHEL 6 : haproxy (RHSA-2013:0729)

critical Nessus Plugin ID 119439

Synopsis

The remote Red Hat host is missing a security update for haproxy.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2013:0729 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL haproxy package based on the guidance in RHSA-2013:0729.
