![]() DC and AC table IDs read in the scan header segment weren't validated against the IDs of Huffman tables read in the DHT segment. This caused an OOB read when a Huffman table was accessed using the ID read in the scan header segment. Furthermore, the decoder now replaces the old DC or AC table if a redefinition has been found prior to the scan header. Fixes #3439. |
