Description Martin Prpič 2016-12-08 09:04:28 UTC

A NULL pointer dereference flaw was found in the way openjpeg decoded certain input images. Due to a logic error in the code responsible for decoding the input image, an application using openjpeg to process image data could crash when processing a crafted image. 

Upstream bug:

https://github.com/uclouvain/openjpeg/issues/863

Upstream patch:

https://github.com/szukw000/openjpeg/commit/7b28bd2b723df6be09fe7791eba33147c1c47d0d

Note that the above patch fixes two issues: CVE-2016-9573 as well as CVE-2016-9572.
