Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : sudo vulnerability (USN-956-1)

medium Nessus Plugin ID 47575

Language:

Synopsis

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

Description

Evan Broder and Anders Kaseorg discovered that sudo did not properly sanitize its environment when configured to use secure_path (the default in Ubuntu). A local attacker could exploit this to execute arbitrary code as root if sudo was configured to allow the attacker to use a program that interpreted the PATH environment variable.

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.

Solution

Update the affected sudo and / or sudo-ldap packages.
