    Package        : hztty
    Vulnerability  : privilege escalation
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : CAN-2005-0019
    Erik Sjölund discovered that hztty, a converter for GB, Big5 and zW/HZ
    Chinese encodings in a tty session, can be triggered to execute
    arbitrary commands with group utmp privileges.
    For the stable distribution (woody) this problem has been fixed in
    version 2.0-5.2woody2.
    For the unstable distribution (sid) this problem has been fixed in
    version 2.0-6.1.
    We recommend that you upgrade your hztty package.
