A flaw was found in OpenJPEG’s encoder. This flaw allows an attacker to pass specially crafted x,y offset input to OpenJPEG to use during encoding. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
