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"
