11th February, 2006
heimdal vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 5.10
- Ubuntu 5.04
- Ubuntu 4.10
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).

- Ubuntu 5.10:
- heimdal-servers
- Ubuntu 5.04:
