Details

Max Justicz discovered that dpkg incorrectly handled unpacking certain
source packages. If a user or an automated system were tricked into
unpacking a specially crafted source package, a remote attacker could
modify files outside the target unpack directory, leading to a denial of
service or potentially gaining access to the system.
