Name of the Vulnerable Software and Affected Versions: Exempi versions prior to 2.5

Description: An issue was discovered in Exempi where the XMPFiles/source/FormatSupport/WEBP Support.cpp file does not check whether a bitstream has a NULL value. This leads to a NULL pointer dereference in the WEBP::VP8XChunk class.

Recommendations: For Exempi versions prior to 2.5, update to version 2.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the WEBP Support.cpp file until a patch is available.
