The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists in the libevt_record_values_read_event() function in libevt_record_values.c due to improper checking of out-of-bounds values of user SID data size, strings size, or data size. A remote attacker can submit a specially crafted EVT file, cause the service to crash or execute arbitrary code.
