Red Hat Product Security has rated this update as having a security
impact of Low. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link (s) in the References section.

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: Out-of-bounds access in pch_write_line function in pch.c
(CVE-2016-10713)

* patch: Double free of memory in pch.c:another_hunk() causes a crash
(CVE-2018-6952)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section.

Additional Changes :

For detailed information on changes in this release, see the Red Hat

Red Hat Product Security has rated this update as having a security
impact of Low. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link (s) in the References section.

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: Out-of-bounds access in pch_write_line function in pch.c
(CVE-2016-10713)

* patch: Double free of memory in pch.c:another_hunk() causes a crash
(CVE-2018-6952)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section.

Additional Changes :

For detailed information on changes in this release, see the Red Hat

for CVE-2019-13638 , but the ! syntax is specific to ed, and is
unrelated to a shell metacharacter.(CVE-2018-20969)

GNU patch through 2.7.6 is vulnerable to OS shell command injection
that can be exploited by opening a crafted patch file that contains an
ed style diff payload with shell metacharacters. The ed editor does
not need to be present on the vulnerable system. This is different
from CVE-2018-1000156 . (CVE-2019-13638)

A heap-based out-of-bounds read flaw was found in the way the patch
utility parsed patch files. An attacker could potentially use this
flaw to crash the patch utility by tricking it into processing crafted
patch files.(CVE-2016-10713)

A double-free flaw was found in the way the patch utility processed
patch files. An attacker could potentially use this flaw to crash the
patch utility by tricking it into processing crafted
patches.(CVE-2018-6952)"
