Package : unzip Vulnerability : race condition Problem type : local Debian-specific: no CVE ID : CAN-2005-2475 BugTraq ID : 14450 Debian Bugs : 321927 343680
The unzip update in DSA 903 contained a regression so that symbolic links that are resolved later in a zip archive aren't supported anymore. This update corrects this behaviour. For completeness, below plese find the original advisory text:
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 5.50-1woody5.
For the stable distribution (sarge) this problem has been fixed in version 5.52-1sarge3.
For the unstable distribution (sid) this problem has been fixed in version 5.52-6.
We recommend that you upgrade your unzip package.
