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).

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

  - 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)

  - 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)

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

  - 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)

  - 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)

This update for patch fixes several issues. These security issues were fixed :

  - CVE-2018-1000156: patch: Malicious patch files cause ed     to execute arbitrary commands (bsc#1088420).

  - CVE-2014-9637: Prevent DoS by remote attackers (memory     consumption and segmentation fault) via a crafted diff     file (bsc#914891).

  - CVE-2016-10713: Prevent out-of-bounds access within     pch_write_line() that could have lead to DoS via a     crafted input file (bsc#1080918).

  - CVE-2010-4651: Fixed a directory traversal bug     (bsc#662957) :

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

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

  - 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)

  - 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)

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.
