DESCRIPTION:
A vulnerability has been reported in HAProxy, which can be exploited
by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error within the
"manage_server_side_cookies()" function in src/proto_http.c when
processing certain cookies, which can be exploited to cause a crash
via a HTTP response containing a specially crafted "Set-Cookie"
header.

Successful exploitation requires that cookie-based persistence is
enabled.

The vulnerability is reported in version 1.4.9 through 1.4.14.

SOLUTION:
Update to version 1.4.15.
