Description Andrej Nemec 2017-12-12 10:15:47 EST

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.

Comment 3 Stefan Cornelius 2017-12-13 07:46:43 EST

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