Debian Security Advisory
DSA-377-1 wu-ftpd -- insecure program execution
- Date Reported:
- 04 Sep 2003
- Affected Packages:
- wu-ftpd
- Vulnerable:
- Yes
- 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)
