libmseed de EarthScope hasta la versión 3.5.4 contiene una vulnerabilidad de lectura fuera de límites en el montón en ms3_detect() en parseutils.c, que lee más allá de los búferes de registros miniSEED 2 truncados. Los atacantes pueden proporcionar un búfer de 40 a 47 bytes que supere MS2_ISVALIDHEADER en msr3_parse() o ms3_detect(), provocando una lectura excesiva de hasta 8 bytes y pudiendo causar la caída del proceso.
