Name of the Vulnerable Software and Affected Versions libgig versions through 20200507

Description The issue is related to a heap-buffer-overflow in the RIFF::List::GetSubList function located in RIFF.cpp. This allows an attacker to cause code execution. The vulnerability can be exploited by a remote attacker to access confidential data, compromise data integrity, and cause a denial of service.
