NewStart CGSL CORE 5.04 / MAIN 5.04 : patch Multiple Vulnerabilities (NS-SA-2019-0223)

high Nessus Plugin ID 131420

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has patch packages installed that are affected by multiple vulnerabilities:

- 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)

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

Solution

Upgrade the vulnerable CGSL patch packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
