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
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
HAProxy is released as a Technology Preview in Red Hat Enterprise Linux 6.
