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

The UDF filesystem implementation in the Linux kernel before 3.18.2 does not ensure that space is available for storing a symlink target's name along with a trailing \0 character, which allows local users to obtain sensitive information via a crafted filesystem image, related to fs/udf/symlink.c and fs/udf/unicode.c.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel 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.
