NewStart CGSL MAIN 7.02 : gpsd Multiple Vulnerabilities (NS-SA-2026-0106)
high Nessus Plugin ID 343586
Synopsis
The remote NewStart CGSL host is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version MAIN 7.02, has gpsd packages installed that are affected by multiple vulnerabilities:- An integer underflow vulnerability exists in the `nextstate()` function in `gpsd/packet.c` of gpsd versions prior to commit `ffa1d6f40bca0b035fc7f5e563160ebb67199da7`. When parsing a NAVCOM packet, the payload length is calculated using `lexer->length = (size_t)c - 4` without checking if the input byte `c` is less than 4. This results in an unsigned integer underflow, setting `lexer->length` to a very large value (near `SIZE_MAX`). The parser then enters a loop attempting to consume this massive number of bytes, causing 100% CPU utilization and a Denial of Service (DoS) condition. (CVE-2025-67269)
- gpsd before commit dc966aa contains a heap-based out-of-bounds write vulnerability in the drivers/driver_nmea2000.c file. The hnd_129540 function, which handles NMEA2000 PGN 129540 (GNSS Satellites in View) packets, fails to validate the user-supplied satellite count against the size of the skyview array (184 elements). This allows an attacker to write beyond the bounds of the array by providing a satellite count up to 255, leading to memory corruption, Denial of Service (DoS), and potentially arbitrary code execution. (CVE-2025-67268)
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 gpsd packages. Note that updated packages may not be available yet. Please contact ZTE for more information.See Also
