Summary
- --------------------------------------------------------------------------Debian Security Advisory DSA 903-1 security@debian.org http://www.debian.org/security/ Martin Schulze November 21st, 2005 http://www.debian.org/security/faq - --------------------------------------------------------------------------Package : unzip Vulnerability : race condition Problem type : local Debian-specific: no CVE ID : CAN-2005-2475 BugTraq ID : 14450 Debian Bug : 321927 Imran Ghory discovered a race condition in the permissions setting code in unzip. When decompressing a file in a directory an attacker has access to, unzip could be tricked to set the file permissions to a different file the user has permissions to. For the old stable distribution (woody) this problem has been fixed in version 5.50-1woody4. For the stable distribution (sarge) this problem has been fixed in version 5.52-1sarge2. For the unstable distribution (sid) this problem has been fixed in version 5.52-4. We recommend that you upgrade your unzip package.
