USN-247-1: Heimdal vulnerability

11 February 2006

Heimdal vulnerability

Releases

Details

A privilege escalation flaw has been found in the heimdal rsh (remote
shell) server. This allowed an authenticated attacker to overwrite
arbitrary files and gain ownership of them.

Please note that the heimdal-servers package is not officially
supported in Ubuntu (it is in the 'universe' component of the
archive). However, this affects you if you use a customized version
built from the heimdal source package (which is supported).

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 5.10
  • heimdal-servers -
Ubuntu 5.04
  • heimdal-servers -
Ubuntu 4.10
  • heimdal-servers -

In general, a standard system update will make all the necessary changes.
