CentOS Errata and Security Advisory CESA-2019:2964

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).

Security Fix(es):

  • patch: do_ed_script in pch.c does not block strings beginning with a ! character (CVE-2018-20969)

  • patch: OS shell command injection when processing crafted patch files (CVE-2019-13638)
