Descriptions

An issue was discovered in HCC Embedded InterNiche NicheStack through 4.3. The tfshnd():tftpsrv.c TFTP packet processing function doesn't ensure that a filename is adequately '\0' terminated; therefore, a subsequent call to strlen for the filename might read out of bounds of the protocol packet buffer (if no '\0' byte exists within a reasonable range).

Se ha detectado un problema en HCC Embedded InterNicheStack versiones hasta 4.3. La función packet processing TFTP tfshnd():tftpsrv.c no asegura que un nombre de archivo esté apropiadamente terminado en "\0"; por lo tanto, una llamada posterior a strlen para el nombre de archivo podría leer fuera de límites del búfer de paquetes del protocolo (si no presenta ningún byte "\0" dentro de un rango razonable).
