An issue was discovered in GNU patch before 2.7.6. Out-of-bounds access within pch_write_line() in pch.c can possibly lead to DoS via a crafted input file.

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2019-2033 advisory.

  - An issue was discovered in GNU patch before 2.7.6. Out-of-bounds access within pch_write_line() in pch.c     can possibly lead to DoS via a crafted input file. (CVE-2016-10713)

  - A double free exists in the another_hunk function in pch.c in GNU patch through 2.7.6. (CVE-2018-6952)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the patch package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A double free exists in the another_hunk function in     pch.c in GNU patch through 2.7.6.(CVE-2018-6952)

  - Directory traversal vulnerability in GNU patch versions     which support Git-style patching before 2.7.3 allows     remote attackers to write to arbitrary files with the     permissions of the target user via a .. (dot dot) in a     diff file name.(CVE-2015-1395)

  - An issue was discovered in GNU patch before 2.7.6.
    Out-of-bounds access within pch_write_line() in pch.c     can possibly lead to DoS via a crafted input     file.(CVE-2016-10713)

  - GNU patch 2.7.2 and earlier allows remote attackers to     cause a denial of service (memory consumption and     segmentation fault) via a crafted diff     file.(CVE-2014-9637)

  - This vulnerability has been modified since it was last     analyzed by the NVD. It is awaiting reanalysis which     may result in further changes to the information     provided.(CVE-2015-1196)

  - 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)

  - do_ed_script in pch.c in GNU patch through 2.7.6 does     not block strings beginning with a ! character. NOTE:
    this is the same commit as for CVE-2019-13638, but the     ! syntax is specific to ed, and is unrelated to a shell     metacharacter.(CVE-2018-20969)

An update of the patch package has been released.

An update for patch is now available for Red Hat Enterprise Linux 7.

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.
