Calendar Grey April 4, 2015
Dist Fedora Esm H88
Essential security updates for Fedora 20 patch tool tackling CVE-2014-9637 and CVE-2015-1196 vulnerabilities.
Security fixes for CVE-2014-9637, CVE-2015-1196, and an infinite loop with a crafted diff.

Summary

The patch program applies diff files to originals. The diff command

is used to compare an original to a changed file. Diff lists the

changes made to the file. A person who has the original file can then

use the patch command with the diff file to add the changes to their

original file (patching the file).

Patch should be installed because it is a common way of upgrading

applications.
