REVISION HISTORY:

Debian GNU/Linux 4.0 (etch).
[***** Start Debian Security Advisory DSA-1438-1 *****]
Several vulnerabilities have been discovered in GNU Tar. The Common Vulnerabilities and Exposures project identifies the following problems:
A directory traversal vulnerability enables attackers using specially crafted archives to extract contents outside the directory tree created by tar.
A stack-based buffer overflow in the file name checking code may lead to arbitrary code execution when processing maliciously crafted archives.
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.
For the unstable distribution (sid), these problems have been fixed in version 1.18-2.
We recommend that you upgrade your tar package.
MD5 checksums of the listed files are available in the original advisory.
