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                < 5.15                     >= 5.15

Description
==========
BEGIN regular expression in the awk script detector in
magic/Magdir/commands uses multiple wildcards with unlimited
repetitions.

Impact
=====
A context-dependent attacker could entice a user to open a specially
crafted 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-5.15"
