libvpx.so is vulnerable to Buffer Overflow. The vulnerability is due to the vp9_alloc_context_buffers function in vp9_alloccommon.c and the vp9_change_config function in vp9_encoder.c. There are no proper validation or handling for dynamic memory allocations when processing certain specially formatted video data via a crafted HTML page and fails to reallocate buffers correctly, allowing an attacker to crash or remotely execute arbitrary code.
