NewStart CGSL MAIN 7.02 : zlib Vulnerability (NS-SA-2026-0111)

medium Nessus Plugin ID 343565

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 7.02, has zlib packages installed that are affected by a vulnerability:

 - zlib versions up to and including 1.3.1.2 include a global buffer overflow in the untgz utility located under contrib/untgz. The vulnerability is limited to the standalone demonstration utility and does not affect the core zlib compression library. The flaw occurs when a user executes the untgz command with an excessively long archive name supplied via the command line, leading to an out-of-bounds write in a fixed- size global buffer. (CVE-2026-22184)

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 zlib packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
