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.
