Ubuntu 8.04 LTS / 8.10 : vinagre vulnerability (USN-689-1)
Medium Nessus Plugin ID 36896
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionAlfredo 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.
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.
SolutionUpdate the affected vinagre package.
