An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FormatSupport/WEBP_Support.cpp does not check whether a bitstream has a NULL value, leading to a NULL pointer dereference in the WEBP::VP8XChunk class.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
