Synopsis
=======
The code for parsing ELF headers in file contains a flaw which may
allow an attacker to execute arbitrary code.

Background
=========
file is a utility used to identify the type of a file.

Affected packages
================
    -------------------------------------------------------------------
     Package        /  Vulnerable  /                        Unaffected
    -------------------------------------------------------------------
  1  sys-apps/file       < 4.12                                >= 4.12

Description
==========
A possible stack overflow has been found in the ELF header parsing code
of file.

Impact
=====
An attacker may be able to create a specially crafted ELF file which,
when processed with file, may allow the execution of arbitrary code.

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-4.12"
