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 please 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.
