CVE-2007-0999
==========================================================
A security issue affects the following Ubuntu releases:

Ubuntu 5.10
Ubuntu 6.06 LTS
Ubuntu 6.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 5.10:
  gnomemeeting                             1.2.2-1ubuntu1.2

Ubuntu 6.06 LTS:
  ekiga                                    2.0.1-0ubuntu6.2

Ubuntu 6.10:
  ekiga                                    2.0.3-0ubuntu3.2

After a standard system upgrade you need to restart Ekiga or reboot your 
computer to effect the necessary changes.

Details follow:

It was discovered that Ekiga had format string vulnerabilities beyond 
those fixed in USN-426-1.  If a user was running Ekiga and listening for 
incoming calls, a remote attacker could send a crafted call request, and 
execute arbitrary code with the user's privileges.
