8 January 2008

opal vulnerability




Jose Miguel Esparza discovered that certain SIP headers were not correctly
validated. A remote attacker could send a specially crafted packet to
an application linked against opal (e.g. Ekiga) causing it to crash, leading
to a denial of service.

Update instructions

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

Ubuntu 7.04
Ubuntu 6.10
Ubuntu 6.06

After a standard system upgrade you need to restart your session to effect
the necessary changes.
