There's a flaw in openjpeg's t2 encoder. An attacker who is able to provide
crafted input to be processed by openjpeg could cause a null pointer
dereference. The highest impact of this flaw is to application availability
(CVE-2020-27842).

A flaw was found in OpenJPEG. This flaw allows an attacker to provide specially
crafted input to the conversion or encoding functionality, causing an
out-of-bounds read. The highest threat from this vulnerability is system
availability (CVE-2020-27843).

There's a flaw in src/lib/openjp2/pi.c of openjpeg. If an attacker is able to
provide untrusted input to openjpeg's conversion/encoding functionality, they
could cause an out-of-bounds read. The highest impact of this flaw is to
application availability (CVE-2020-27845).");
