NewStart CGSL MAIN 7.02 : patch Multiple Vulnerabilities (NS-SA-2025-0205)

high Nessus Plugin ID 242710

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 7.02, 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)

- GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time.
(CVE-2018-1000156)

- An issue was discovered in GNU patch through 2.7.6. There is a segmentation fault, associated with a NULL pointer dereference, leading to a denial of service in the intuit_diff_type function in pch.c, aka a mangled rename issue. (CVE-2018-6951)

- A double free exists in the another_hunk function in pch.c in GNU patch through 2.7.6. (CVE-2018-6952)

Note that Nessus has not tested for these issues 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.
