Mandrake Linux Security Advisory : zlib (MDKSA-2002:022)

This script is Copyright (C) 2004-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandrake Linux host is missing one or more security
updates.

Description :

Matthias Clasen found a security issue in zlib that, when provided
with certain input, causes zlib to free an area of memory twice. This
'double free' bug can be used to crash any programs that take
untrusted compressed input, such as web browsers, email clients, image
viewing software, etc. This vulnerability can be used to perform
Denial of Service attacks and, quite possibly, the execution of
arbitrary code on the affected system.

MandrakeSoft has published two advisories concerning this incident :

MDKSA-2002:022 - zlib MDKSA-2002:023 - packages containing zlib

The second advisory contains additional packages that bring their own
copies of the zlib source, and as such need to be fixed and rebuilt.
Updating the zlib library is sufficient to protect those programs that
use the system zlib, but the packages as noted in MDKSA-2002:023 will
need to be updated for those packages that do not use the system zlib.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
