Synopsis
========
A vulnerability in file could result in Denial of Service.

Background
==========
file is a utility that guesses a file format by scanning binary data
for patterns.

Affected packages
=================

Description
===========
Multiple out-of-bounds read errors and invalid pointer dereference
errors have been found in cdf.c.

Impact
======

Composite Document File (CDF) using file, possibly resulting in a
Denial of Service condition.

Workaround

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/file-5.11"
