A vulnerability was found while fuzzing libbpg 0.9.7. It is a NULL pointer dereference issue due to missing check of the return value of function malloc in the BPG encoder. This vulnerability appeared while converting a malicious JPEG file to BPG.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product dereferences a pointer that it expects to be valid but is NULL.
