Description:
According to a bug report from Jim Meyering [0], a remote overflow
exists in the GNU Tape Archiver (Tar). GNU Tar fails to properly
handle PAX extended headers resulting in a buffer overflow. With a
specially crafted Tar format archive, an attacker can cause arbitrary
command execution when the victim lists the Tar contents or extracts
the archive. The Common Vulnerabilities and Exposures (CVE) project
assigned the id CVE-2006-0300 [2] to the problem.
