Debian DSA-185-1 : heimdal - buffer overflow

critical Nessus Plugin ID 15022

Synopsis

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

Description

A stack-based buffer overflow in the kadm_ser_wrap_in function in the Kerberos v4 administration server was discovered, which is provided by Heimdal as well. A working exploit for this kadmind bug is already circulating, hence it is considered serious. The broken library also contains a vulnerability which could lead to another root exploit.

These problems have been fixed in version 0.4e-7.woody.5 for the current stable distribution (woody), in version 0.2l-7.6 for the old stable distribution (potato) and in version 0.4e-22 for the unstable distribution (sid).

Solution

Upgrade the heimdal packages immediately.
