Package name zlib-pkgs Date March 13th, 2002 Advisory ID MDKSA-2002:023-1 Affected versions 7.1, 7.2, 8.0, 8.1, CS1.0 Synopsis Updated zlib-related packages fix double free vulnerability

Problem 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

Update:

Additional package are now available. For a list of prior packages
released, please see MDKSA-2002:023. The noted packages below are in
addition to MDKSA-2002:023; no packages have been replaced.
