Multiple security issues have been found in HAProxy, a load-balancing reverse proxy:
Buffer overflow in the header capture code.
Buffer overflow in the HTTP keepalive code.
Denial of service in parsing HTTP headers.
For the oldstable distribution (squeeze), these problems have been fixed in version 1.4.8-1+squeeze1.
The stable distribution (wheezy) doesn't contain haproxy.
For the unstable distribution (sid), these problems have been fixed in version 1.4.24-1.
We recommend that you upgrade your haproxy packages.
