NewStart CGSL MAIN 7.02 : c-ares Vulnerability (NS-SA-2025-0075)

medium Nessus Plugin ID 238010

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

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

 - c-ares is a C library for asynchronous DNS requests. `ares__read_line()` is used to parse local configuration files such as `/etc/resolv.conf`, `/etc/nsswitch.conf`, the `HOSTALIASES` file, and if using a c-ares version prior to 1.27.0, the `/etc/hosts` file. If any of these configuration files has an embedded `NULL` character as the first character in a new line, it can lead to attempting to read memory prior to the start of the given buffer which may result in a crash. This issue is fixed in c-ares 1.27.0.
 No known workarounds exist. (CVE-2024-25629)

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