Debian DSA-385-1 : hztty - buffer overflows

high Nessus Plugin ID 15222

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

For the stable distribution (woody) this problem has been fixed in version 2.0-5.2woody1.

We recommend that you update your hztty package.
