Debian DSA-1817-1 : ctorrent - stack-based buffer overflow

high Nessus Plugin ID 39440

Synopsis

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

Description

Michael Brooks discovered that ctorrent, a text-mode bittorrent client, does not verify the length of file paths in torrent files. An attacker can exploit this via a crafted torrent that contains a long file path to execute arbitrary code with the rights of the user opening the file.

The oldstable distribution (etch) does not contain ctorrent.

Solution

Upgrade the ctorrent packages.

For the stable distribution (lenny), this problem has been fixed in version 1.3.4-dnh3.2-1+lenny1.
