dpkg -- stack-based buffer overflow

Salvatore Bonaccorso reports:

Hanno Boeck discovered a stack-based buffer overflow in the
dpkg-deb component of dpkg, the Debian package management system.
This flaw could potentially lead to arbitrary code execution if a
user or an automated system were tricked into processing a specially
crafted Debian binary package (.deb) in the old style Debian binary
package format.
