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.");
