Debian DSA-377-1 : wu-ftpd - insecure program execution
High Nessus Plugin ID 15214
SynopsisThe remote Debian host is missing a security-related update.
Descriptionwu-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.
SolutionFor the stable distribution (woody) this problem has been fixed in version 2.6.2-3woody2.
We recommend that you update your wu-ftpd package.
