NewStart CGSL MAIN 6.06 : glibc Multiple Vulnerabilities (NS-SA-2023-0076)
critical Nessus Plugin ID 187336
Synopsis
The remote NewStart CGSL host is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version MAIN 6.06, has glibc packages installed that are affected by multiple vulnerabilities:- A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system. (CVE-2021-3999)
- The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its path argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution. (CVE-2022-23218)
- The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its hostname argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution. (CVE-2022-23219)
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 glibc packages. Note that updated packages may not be available yet. Please contact ZTE for more information.See Also
