Debian DSA-765-1 : heimdal - buffer overflow

high Nessus Plugin ID 19270

Synopsis

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

Description

Gael Delalleau discovered a buffer overflow in the handling of the LINEMODE suboptions in telnet clients. Heimdal, a free implementation of Kerberos 5, also contains such a client. This can lead to the execution of arbitrary code when connected to a malicious server.

Solution

Upgrade the heimdal package.

For the old stable distribution (woody) this problem has been fixed in version 0.4e-7.woody.11.

For the stable distribution (sarge) this problem has been fixed in version 0.6.3-10.
