Synopsis :

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

Description :

wu-ftpd, an FTP server, implements a feature whereby multiple files
can be fetched in the form of a dynamically constructed archive file,
such as a tar archive. The names of the files to be included are
passed as command line arguments to tar, without protection against
them being interpreted as command-line options. GNU tar supports
several command line options which can be abused, by means of this
vulnerability, to execute arbitrary programs with the privileges of
the wu-ftpd process.

Georgi Guninski pointed out that this vulnerability exists in Debian
woody.

Solution :

For the stable distribution (woody) this problem has been fixed in
version 2.6.2-3woody2.

We recommend that you update your wu-ftpd package.

Risk factor :

High / CVSS Base Score : 7.5
