Synopsis
=======
A vulnerability in file could lead to a Denial of Service condition.

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               < 5.33-r2                 >= 5.33-r2 

Description
==========
File does not properly utilize the do_core_note function in readelf.c
in libmagic.a.

Impact
=====
A remote attacker could send a specially crafted ELF 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-5.33-r2"
