Synopsis
========

Vulnerabilities in file could allow a context-dependent attack to
create a Denial of Service condition.

Background
==========

The file utility attempts to identify a file’s format by scanning
binary data for patterns.

Affected packages
=================

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 sys-apps/file < 5.22 >= 5.22

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

Multiple issues with the ELF parser used by the file utility have been
detected and fixed.

Impact
======

A context-dependent attacker can cause Denial of Service.

Workaround

# emerge –sync
# emerge –ask –oneshot –verbose “>=sys-apps/file-5.22”
