Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : sudo vulnerability (USN-2533-1)

Low Nessus Plugin ID 81881


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


Jakub Wilk and Stephane Chazelas discovered that Sudo incorrectly handled the TZ environment variable. An attacker with Sudo access could possibly use this issue to open arbitrary files, bypassing intended permissions.

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.
