Arch Linux Security Advisory ASA-201811-14 ========================================== Severity: High Date : 2018-11-12 CVE-ID : CVE-2018-6952 CVE-2018-1000156 Package : patch Type : multiple issues Remote : No Link : Summary ======= The package patch before version 2.7.6-7 is vulnerable to multiple issues including arbitrary command execution and denial of service. Resolution ========== Upgrade to 2.7.6-7. # pacman -Syu "patch>=2.7.6-7" The problems have been fixed upstream but no release is available yet. Workaround ========== None. Description =========== - CVE-2018-6952 (denial of service) A double free exists in the another_hunk function in pch.c in GNU patch through 2.7.6. An attacker could potentially use this flaw to crash the patch utility by tricking it into processing crafted patches. - CVE-2018-1000156 (arbitrary command execution) An arbitrary command execution vulnerability has been found in patch versions prior to 2.7.7 when applying ed-style patches. Due to insufficient sanitization of the input patch stream, it is possible for a patch file to cause patch to pass certain ed scripts to the ed editor, which would run commands. This issue could be exploited to execute arbitrary commands as the user invoking patch against a specially crafted patch file, which could be leveraged to obtain elevated privileges. Impact ====== An attacker can execute arbitrary commands via a specially crafted patch file. References ==========
