Overview

CVE-2013-0157 is a low-severity vulnerability affecting kernel util-linux. It was published on January 21, 2014 and has a CVSS 2.0 base score of 2.1 (LOW).

This vulnerability has a CVSS 2.0 base score of 2.1, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

(a) mount and (b) umount in util-linux 2.14.1, 2.17.2, and probably other versions allow local users to determine the existence of restricted directories by (1) using the --guess-fstype command-line option or (2) attempting to mount a non-existent device, which generates different error messages depending on whether the directory exists.

Remediation

Check the references section for vendor advisories and patches from kernel. Update util-linux to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
