RHEL 2.1 : zlib (RHSA-2003:081)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated zlib packages that fix a buffer overflow vulnerability are now
available.

Zlib is a general-purpose, patent-free, lossless data compression
library that is used by many different programs.

The function gzprintf within zlib, when called with a string longer
than Z_PRINTF_BUFZISE (= 4096 bytes), can overflow without giving a
warning.

zlib-1.1.4 and earlier exhibit this behavior. There are no known
exploits of the gzprintf overrun, and only a few programs, including
rpm2html and gimp-print, are known to use the gzprintf function.

The problem has been fixed by checking the length of the output string
within gzprintf.
