Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
Michael Calmer and Marcus Meissner discovered that several krb5 tools
did not check the return values from setuid() system calls. On systems
that have configured user process limits, it may be possible for an
attacker to cause setuid() to fail via resource starvation. In that
situation, the tools will not reduce their privilege levels, and will
continue operation as the root user.
By default, Ubuntu does not ship with user process limits.
Please note that these packages are not officially supported by Ubuntu
(they are in the 'universe' component of the archive).
Update the affected packages.
