Date:  Fri, 27 May 2005 19:41:55 +0200 (CEST)

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 730-1 Martin Schulze May 27th, 2005 - -------------------------------------------------------------------------- Package : bzip2 Vulnerability : race condition Problem-Type : local Debian-specific: no CVE ID : CAN-2005-0953 Debian Bug : 303300 Imran Ghory discovered a race condition in bzip2, a high-quality block-sorting file compressor and decompressor. When decompressing a file in a directory an attacker has access to, bunzip2 could be tricked to set the file permissions to a different file the user has permissions to. For the stable distribution (woody) this problem has been fixed in version 1.0.2-1.woody2 For the testing distribution (sarge) this problem has been fixed in version 1.0.2-6. For the unstable distribution (sid) this problem has been fixed in version 1.0.2-6. We recommend that you upgrade your bzip2 packages. 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.
