-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 959-1 security@debian.org http://www.debian.org/security/ Martin Schulze January 30th, 2006 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : unalz Vulnerability : buffer overflow Problem-Type : local (remote) Debian-specific: no CVE ID : CVE-2005-3862 Debian Bug : 340842 Ulf Härnhammer from the Debian Audit Project discovered that unalz, a decompressor for ALZ archives, performs insufficient bounds checking when parsing file names. This can lead to arbitrary code execution if an attacker provides a crafted ALZ archive. The old stable distribution (woody) does not contain unalz. For the stable distribution (sarge) this problem has been fixed in version 0.30.1 For the unstable distribution (sid) this problem will be fixed soon. We recommend that you upgrade your unalz package. Upgrade Instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
