In OpenJPEG 2.3.0, a stack-based buffer overflow was discovered in the pgxtoimage function in jpwl/convert.c. The vulnerability causes an out-of-bounds write, which may lead to denial of service or possibly code execution. Upstream issue: https://github.com/uclouvain/openjpeg/issues/1044

Mitigated by stack canaries, so code execution should be very hard and in general, this should be limited to a crash.
