Date Reported:
04 Sep 2003
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-1999-0997.
More information:

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.

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

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you update your wu-ftpd package.

Fixed in:

Debian GNU/Linux 3.0 (woody)
