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

  - 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)

  - 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)

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - patch: directory traversal via file rename (CVE-2015-1395)

  - GNU patch 2.7.1 allows remote attackers to write to arbitrary files via a symlink attack in a patch file.
    (CVE-2015-1196)

  - In GNU patch through 2.7.6, the following of symlinks is mishandled in certain cases other than input     files. This affects inp.c and util.c. (CVE-2019-13636)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Updated patch package fixes security vulnerabilities :

It was reported that a crafted diff file can make patch eat memory and later segfault (CVE-2014-9637).

It was reported that the versions of the patch utility that support Git-style patches are vulnerable to a directory traversal flaw. This could allow an attacker to overwrite arbitrary files by applying a specially crafted patch, with the privileges of the user running patch (CVE-2015-1395).

GNU patch before 2.7.4 allows remote attackers to write to arbitrary files via a symlink attack in a patch file (CVE-2015-1196).

The GNU patch utility was updated to 2.7.5 to fix three security issues and one non-security bug.

The following vulnerabilities were fixed :

  - CVE-2015-1196: directory traversal flaw when handling     git-style patches. This could allow an attacker to     overwrite arbitrary files by tricking the user into     applying a specially crafted patch. (bsc#913678)

  - CVE-2015-1395: directory traversal flaw when handling     patches which rename files. This could allow an attacker     to overwrite arbitrary files by tricking the user into     applying a specially crafted patch. (bsc#915328)

  - CVE-2015-1396: directory traversal flaw via symbolic     links. This could allow an attacker to overwrite     arbitrary files by tricking the user into applying a by     applying a specially crafted patch. (bsc#915329)

The following bug was fixed :

  - bsc#904519: Function names in hunks (from diff -p) are     now preserved in reject files.

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)

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2651-1 advisory.

    Jakub Wilk discovered that GNU patch did not correctly handle file paths in patch files. An attacker could     specially craft a patch file that could overwrite arbitrary files with the privileges of the user invoking     the program. This issue only affected Ubuntu 12.04 LTS. (CVE-2010-4651)

    Lszl Bszrmnyi discovered that GNU patch did not correctly handle some patch files. An attacker     could specially craft a patch file that could cause a denial of service. (CVE-2014-9637)

    Jakub Wilk discovered that GNU patch did not correctly handle symbolic links in git style patch files. An     attacker could specially craft a patch file that could overwrite arbitrary files with the privileges of     the user invoking the program. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2015-1196)

    Jakub Wilk discovered that GNU patch did not correctly handle file renames in git style patch files. An     attacker could specially craft a patch file that could overwrite arbitrary files with the privileges of     the user invoking the program. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2015-1395)

    Jakub Wilk discovered the fix for CVE-2015-1196 was incomplete for GNU patch. An attacker could specially     craft a patch file that could overwrite arbitrary files with the privileges of the user invoking the     program. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2015-1396)
