The following packages are affected: dia dia-gnome
Several format string vulnerabilities have been discovered in dia. By tricking a user into opening a specially crafted dia file, or a file with a specially crafted name, this could be exploited to execute arbitrary code with the user's privileges.
Solution: The problem can be corrected by upgrading the affected package to version 0.94.0-5ubuntu1.3 (for Ubuntu 5.04), or 0.94.0-11ubuntu1.2 (for Ubuntu 5.10). After doing a standard system upgrade you need to restart dia to effect the necessary changes.
