The vulnerability allows a remote attacker to cause a denial of service and disclose sensitive information.
The vulnerability exists due to out-of-bounds read in LossyDctDecoder_execute when decompressing DWAA-packed scan-line EXR files with a maliciously forged chunk. A remote attacker can supply a specially crafted EXR file to cause a denial of service and disclose sensitive information.
