Ubuntu 6.06 LTS / 6.10 / 7.04 : opal vulnerability (USN-562-1)

Medium Nessus Plugin ID 29918


The remote Ubuntu host is missing one or more security-related patches.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
