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
