Description Andrej Nemec 2017-07-19 15:20:48 UTC
JasPer is vulnerable to a NULL pointer exception in the function jp2_encode which failed to check to see if the image contained at least one component resulting in a denial-of-service.

Upstream bug report:

https://github.com/mdadams/jasper/issues/120

Upstream commit:

https://github.com/mdadams/jasper/commit/58ba0365d911b9f9dd68e9abf826682c0b4f2293

The fix is included in version 2.0.13.

This bug is in encoder, therefore applications that only use jasper to read JPEG2000 images are not affected, it only affects applications that read untrusted images and convert them to JPEG2000 format using jasper.
