NVD Description
Note: Versions mentioned in the description apply only to the upstream rtklib package and not the rtklib package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
RTKLIB through 2.4.3 contains an out-of-bounds write vulnerability in decode_type1033 function that fails to clamp length counters to destination buffer size, allowing up to 191-byte overflow into fixed 64-byte descriptor fields. An attacker controlling an NTRIP or serial RTCM3 correction stream can craft a valid CRC-bearing type-1033 message to corrupt adjacent rtcm_t object members, potentially achieving arbitrary code execution or denial of service.
