unzip - directory traversal

A directory traversal vulnerability in UnZip 5.50 allows attackers to
bypass a check for relative pathnames (“…/”) by placing certain invalid
characters between the two “.” characters. The fix which was
implemented in DSA-344-1 may not have protected against all methods of
exploiting this vulnerability.

For the stable distribution (woody) this problem has been fixed in
version 5.50-1woody2.

For the unstable distribution (sid) this problem has been fixed in
version 5.50-3.

We recommend that you update your unzip package.
