Ubuntu 9.10 / 10.04 LTS : sudo vulnerability (USN-983-1)

Medium Nessus Plugin ID 49140


The remote Ubuntu host is missing one or more security-related patches.


Markus Wuethrich discovered that sudo did not always verify the user when a group was specified in the Runas_Spec. A local attacker could exploit this to execute arbitrary code as root if sudo was configured to allow the attacker to use a program as a group when the attacker was not a part of that group.

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 sudo and / or sudo-ldap packages.
