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
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  sys-apps/file                 < 5.11                     >= 5.11

Description
===========

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

Impact
======

A remote attacker could entice a user to open a specially crafted
Composite Document File (CDF) using file, possibly resulting in a
Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All file users should upgrade to the latest version:

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