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.
