    1. Summary:
    
    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.
    
    2. Relevant releases/architectures:

    3. 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.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
