Name of the Vulnerable Software and Affected Versions libIEC61850 version 1.3.1

Description A memory leak issue has been identified. The Memory malloc function in hal/memory/lib memory.c leaks memory when called from Asn1PrimitiveValue create in mms/asn1/asn1 ber primitive value.c. This issue is demonstrated by examples such as goose publisher example.c and iec61850 9 2 LE example.c.
