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


Several vulnerabilities have been discovered in GNU Tar. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2007-4131 A directory traversal vulnerability enables attackers using specially crafted archives to extract contents outside the directory tree created by tar.

- CVE-2007-4476 A stack-based buffer overflow in the file name checking code may lead to arbitrary code execution when processing maliciously crafted archives.


Upgrade the tar package.
