Detailed vulnerability description
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists in the Chunk class in the source code file XMPFiles/source/FormatSupport/RIFF.cpp due to integer overflow and infinite loop when handling Extensible Metadata Platform (XMP) data in .avifiles. A remote attacker can trick the victim into accessing a specially crafted .avi file, trigger memory corruption and cause the service to crash.
