Date Reported:

Affected Packages:
unzip
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CAN-2003-0282.
More information:

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.

Fixed in:

Debian GNU/Linux 3.0 (woody)
