Package        : apache
Problem type   : remote DoS / exploit
Debian-specific: no
CVE name       : CAN-2002-0392
CERT advisory  : VU#944335

Mark Litchfield found a denial of service attack in the Apache
web-server. While investigating the problem the Apache Software
Foundation discovered that the code for handling invalid requests which
use chunked encoding also might allow arbitrary code execution on 64
bit architectures.

This has been fixed in version 1.3.9-14.1 of the Debian apache package,
as well as upstream versions 1.3.16 and 2.0.37. We strongly recommend
that you upgrade your apache package immediately.

Debian GNU/Linux 2.2 alias potato
- - ---------------------------------

  Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
