More information:

Ulf Härnhammar discovered a buffer overflow in lftp, a set of sophisticated command-line FTP/HTTP client programs. An attacker could create a carefully crafted directory on a website so that the execution of an 'ls' or 'rels' command would lead to the execution of arbitrary code on the client machine.

For the stable distribution (woody) this problem has been fixed in version 2.4.9-1woody2.

For the unstable distribution (sid) this problem has been fixed in version 2.6.10-1.

Fixed in:

Debian GNU/Linux 3.0 (woody)
