New! Plugin Severity Now Using CVSS v3

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.

For the old stable distribution (sarge), these problems have been fixed in version 1.14-2.4.

For the stable distribution (etch), these problems have been fixed in version 1.16-2etch1.
