Synopsis
========

A vulnerability 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 < 5.21 >= 5.21

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

An issue with the ELF parser used by the file utility can cause a
resource consumption when reading a specially-crafted ELF binary.

Impact
======

A context-dependent attacker may be able to cause Denial of Service.

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-5.21”
