1) Information disclosure

EUVDB-ID: #VU32438

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2014-9680

CWE-ID: CWE-200 - Information Exposure

Exploit availability: No

Description

The vulnerability allows a local authenticated user to gain access to sensitive information.

sudo before 1.8.12 does not ensure that the TZ environment variable is associated with a zoneinfo file, which allows local users to open arbitrary files for read access (but not view file contents) by running a program within an sudo session, as demonstrated by interfering with terminal output, discarding kernel-log messages, or repositioning tape drives.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Sudo: 1.8.0 - 1.8.11p2
