    Package        : hztty
    Vulnerability  : buffer overflows
    Problem-Type   : local
    Debian-specific: no
    CVE Ids        : CAN-2003-0783
    
    Jens Steube reported a pair of buffer overflow vulnerabilities in
    hztty, a program to translate Chinese character encodings in a
    terminal session.  These vulnerabilities could be exploited by a local
    attacker to gain root privileges on a system where hztty is installed.
    
    Additionally, hztty had been incorrectly installed setuid root, when
    it only requires the privileges of group utmp.  This has also been
    corrected in this update.
    
    For the stable distribution (woody) this problem has been fixed in
    version 2.0-5.2woody1.
    
    For the unstable distribution (sid) this problem will befixed in
    version 2.0-6.
    
    We recommend that you update your hztty package.
