USN-689-1: Vinagre vulnerability

Releases

• Ubuntu 8.10
• Ubuntu 8.04

Packages

• vinagre -

Details

Alfredo Ortega discovered a flaw in Vinagre's use of format strings. A
remote attacker could exploit this vulnerability if they tricked a user
into connecting to a malicious VNC server, or opening a specially crafted
URI with Vinagre. In Ubuntu 8.04, it was possible to execute arbitrary
code with user privileges. In Ubuntu 8.10, Vinagre would simply abort,
leading to a denial of service.

Update instructions

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

Ubuntu 8.10

• vinagre - 2.24.1-0ubuntu1.1

Ubuntu 8.04

• vinagre - 0.5.1-0ubuntu1.1

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