Ubuntu 7.10 / 8.04 LTS : yelp vulnerability (USN-638-1)

Critical Nessus Plugin ID 34059


The remote Ubuntu host is missing a security-related patch.


Aaron Grattafiori discovered that the Gnome Help Viewer did not handle format strings correctly when displaying certain error messages. If a user were tricked into opening a specially crafted URI, a remote attacker could execute arbitrary code with user privileges.

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 yelp package.
