Linux Distros Unpatched Vulnerability : CVE-2014-9731

medium Nessus Plugin ID 218611

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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. (CVE-2014-9731)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
