Description
An issue was discovered in kosma minmea 0.3.0. The minmea_scan functions format specifier copies NMEA field data to a caller-provided buffer without a size parameter. Applications using minmea_scan on untrusted input are vulnerable to a stack buffer overflow.
A stack buffer overflow vulnerability has been identified in Kosma Minmea version 0.3.0. The issue arises in the 'minmea_scan' function, where the format specifier copies NMEA field data to a user-provided buffer without specifying a size limit. This flaw allows for a buffer overflow when the function processes untrusted input, potentially leading to arbitrary code execution.
