|Gentoo Linux Security Advisory
Title: HAProxy: Arbitrary code execution (GLSA 201301-02)
Date: January 08, 2013
A buffer overflow in HAProxy may allow execution of arbitrary code.
HAProxy is a TCP/HTTP reverse proxy for high availability environments.
Vulnerable: < 1.4.21
Unaffected: >= 1.4.21
Architectures: All supported architectures
A boundary error in HAProxy could cause a buffer overflow when header
rewriting is enabled and the configuration sets global.tune.bufsize to a
value greater than the default (16384 bytes).
A remote attacker could possibly execute arbitrary code with the
privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All HAProxy users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/haproxy-1.4.21"
