Synopsis

Moderate: haproxy security update

Type/Severity

Security Advisory Moderate

Topic

An updated haproxy package that fixes one security issue is now available for Red Hat OpenShift Enterprise 1.2.2.

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.

Description

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

A flaw was found in the way HAProxy handled requests when the proxy's configuration ("/etc/haproxy/haproxy.cfg") had certain rules that use the hdr_ip criterion. A remote attacker could use this flaw to crash HAProxy instances that use the affected configuration. (CVE-2013-2175)

In Red Hat OpenShift Enterprise, the HAProxy cartridge is added to your application when you select to have your application scaled.

Red Hat would like to thank HAProxy upstream for reporting this issue. Upstream acknowledges David Torgerson as the original reporter.

Users of Red Hat OpenShift Enterprise 1.2.2 are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
