8th March, 2007
ekiga, gnomemeeting vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.10
- Ubuntu 6.06 LTS
- Ubuntu 5.10
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.10:
- ekiga 2.0.3-0ubuntu3.2
- Ubuntu 6.06 LTS:
- ekiga 2.0.1-0ubuntu6.2
- Ubuntu 5.10:
- gnomemeeting 1.2.2-1ubuntu1.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart Ekiga or reboot your
computer to effect the necessary changes.
