|Title:||Ubuntu USN-253-1 (heimdal)|
|Summary:||Ubuntu USN-253-1 (heimdal)|
The remote host is missing an update to heimdal
announced via advisory USN-253-1.
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)
The following packages are affected: heimdal-servers
A remote Denial of Service vulnerability was discovered in the heimdal
implementation of the telnet daemon. A remote attacker could force the
server to crash due to a NULL de-reference before the user logged in,
resulting in inetd turning telnetd off because it forked too fast.
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).
The problem can be corrected by upgrading the affected package to
version 0.6.2-3ubuntu0.3 (for Ubuntu 4.10), 0.6.3-7ubuntu1.3 (for
Ubuntu 5.04), or 0.6.3-11ubuntu1.2 (for Ubuntu 5.10). In general, a
standard system upgrade is sufficient to effect the necessary changes.
