Debian DSA-344-2 : unzip - directory traversal

low Nessus Plugin ID 15181

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

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

We recommend that you update your unzip package.
