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

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

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

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
