USN-983-1: Sudo vulnerability
7 September 2010
Under non-default configurations, a local user could run programs with administrator privileges.
Releases
Packages
- sudo - Provide limited super user privileges to specific users
Details
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.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 9.10
Ubuntu 10.04
In general, a standard system update will make all the necessary changes.
