RedHat: RHSA-2013-1204:01 Moderate: haproxy security update
Summary
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.
