Message-ID: <m1Ds131-000ojEC@finlandia.Infodrom.North.DE> Date: Mon Jul 11 17:27:38 2005 From: joey at infodrom.org (Martin Schulze) Subject: [SECURITY] [DSA 752-1] New gzip packages fix several vulnerabilities -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 752-1 security@...ian.org http://www.debian.org/security/ Martin Schulze July 11th, 2005 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : gzip Vulnerability : several Problem-Type : local (remote) Debian-specific: no CVE ID : CAN-2005-0988 CAN-2005-1228 Debian Bug : 305255 Two problems have been discovered in gzip, the GNU compression utility. The Common Vulnerabilities and Exposures project identifies the following problems. CAN-2005-0988 Imran Ghory discovered a race condition in the permissions setting code in gzip. When decompressing a file in a directory an attacker has access to, gunzip could be tricked to set the file permissions to a different file the user has permissions to. CAN-2005-1228 Ulf H?rnhammar discovered a path traversal vulnerability in gunzip. When gunzip is used with the -N option an attacker could this vulnerability to create files in an arbitrary directory with the permissions of the user. For the oldstable distribution (woody) these problems have been fixed in version 1.3.2-3woody5. For the stable distribution (sarge) these problems have been fixed in version 1.3.5-10. For the unstable distribution (sid) these problems have been fixed in version 1.3.5-10. We recommend that you upgrade your gzip package.
