The remote Red Hat host is missing one or more security updates.
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.
