| Package | : | unzip |
| Vulnerability | : | directory traversal |
| Problem-Type | : | local |
| Debian-specific | : | no |
| CVE Ids | : | CAN-2003-0282 |
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.
