Synopsis
========

Patch is vulnerable to a locally generated Denial of Service condition.

Background
==========

Patch takes a patch file containing a difference listing produced by
the diff program and applies those differences to one or more original
files, producing patched versions.

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

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 sys-devel/patch < 2.7.4 >= 2.7.4

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

Due to a flaw in Patch, the application can enter an infinite loop when
processing a specially crafted diff file.

Impact
======

A local attacker could pass a specially crafted diff file to Patch,
possibly resulting in a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All patch users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=sys-devel/patch-2.7.4”

References
==========

Availability
============

This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:

https://security.gentoo.org/glsa/201612-12

Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users’ machines is of utmost
