hztty - buffer overflows



Debian Security Advisory

DSA-385-1 hztty -- buffer overflows

Date Reported:
18 Sep 2003
Affected Packages:
hztty
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CAN-2003-0783.
More information:

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 be fixed in version 2.0-6.

We recommend that you update your hztty package.

Fixed in:

Debian GNU/Linux 3.0 (woody)
