It has been developed in order to promote the use of JPEG 2000, a still-image compression standard from the Joint Photographic Experts Group (JPEG). Since April 2015, it is officially recognized by ISO/IEC and ITU-T as a JPEG 2000 Reference Software.\r\n\r\nSecurity Fix(es):\r\n\r\nA 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.(CVE-2020-27823)\r\n\r\nA flaw was found in OpenJPEG’s encoder in the opj_dwt_calc_explicit_stepsizes() function.
