2.3.1. The vulnerability causes an out-of-bounds write, which may lead to
remote denial of service or possibly remote code execution (CVE-2020-27814).

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 (CVE-2020-27823).

There is a flaw in openjpeg's encoder in the opj_dwt_calc_explicit_stepsizes()
function. An attacker who is able to supply crafted input to decomposition
levels could cause a buffer overflow, potentially causing an impact to
application availability (CVE-2020-27824).");
