Gentoo Linux Security Advisory GLSA 200508-01
Severity: High
Title: Compress::Zlib: Buffer overflow
Date: August 01, 2005
Bugs: #100540
ID: 200508-01
Synopsis
Compress::Zlib is vulnerable to a buffer overflow which could
potentially lead to execution of arbitrary code.
Background
The Compress::Zlib is a Perl module which provides an interface
to the zlib compression library.
Affected packages
Package / Vulnerable / Unaffected
1 dev-perl/Compress-Zlib < 1.35 >= 1.35
Description
Compress::Zlib 1.34 contains a local vulnerable version of zlib,
which may lead to a buffer overflow.
Impact
By creating a specially crafted compressed data stream,
attackers can overwrite data structures for applications that use
Compress::Zlib, resulting in a Denial of Service and potentially
arbitrary code execution.
Workaround
There is no known workaround at this time.
Resolution
All Compress::Zlib users should upgrade to the latest
version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-perl/Compress-Zlib-1.35"
