NewStart CGSL MAIN 6.02 : glibc Vulnerability (NS-SA-2022-0067)

critical Nessus Plugin ID 160844

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has glibc packages installed that are affected by a vulnerability:

 - The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations. (CVE-2021-35942)

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