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.
