Comment 4 Tomas Hoger 2017-03-30 21:29:24 UTC

The original problem was with integer overflows, which lead to out-of-bounds access.  That problem was originally addressed in jasper version 2.0.0 via this commit:

https://github.com/mdadams/jasper/commit/aa0b0f79ade5eef8b0e7a214c03f5af54b36ba7d

Shortly after the above commit, it was found that it introduced a bug into the jpc_pi_nextrpcl() function, which was corrected via this commit (still in version 2.0.0):

https://github.com/mdadams/jasper/commit/f25486c3d4aa472fec79150f2c41ed4333395d3d

These commits were apparently triggered by this upstream bug:

https://github.com/mdadams/jasper/issues/94


This upstream bug:

https://github.com/mdadams/jasper/issues/103

reports similar issue to what was fixed in the jpc_pi_nextrpcl() function via f25486c, this time in the jpc_pi_nextpcrl() function.  This was corrected upstream via this commit (also linked in comment 0 above):

https://github.com/mdadams/jasper/commit/99a50593254d1b53002719bbecfc946c84b23d27

This fix was included in upstream jasper version 2.0.6.
