Comment 3 Tomas Hoger 2017-03-31 11:49:50 UTC 
This is a problem in JPC encoder, so can be triggered if malicious image is converted by jasper, it does not affect use cases when jasper is only used to read / decode images.

The problem is that certain pointer variables are not set to NULL after calls to free(), and the code may attempt to free the memory again, leading to double-free or use-after-free.

This issue was fixed upstream via this commit:

https://github.com/mdadams/jasper/commit/03fe49ab96bf65fea784cdc256507ea88267fc7c

The fix is included in upstream version 2.0.12.
