Title
Excessive memory allocation during VP8L decoding in golang.org/x/image
Summary
VP8L decoding in golang.org/x/image/vp8l can allocate an excessive amount of memory when processing a crafted VP8L image containing many unused Huffman tree groups. This allows a remote attacker to cause a denial of service via memory exhaustion.
Severity
