Comment 3 Tomas Hoger 2017-03-02 22:54:57 UTC

This issue was reported upstream in:

https://github.com/mdadams/jasper/issues/49
https://github.com/mdadams/jasper/issues/53

It was first incorrectly fixed in version jasper 1.900.13 by protecting against integer overflows in jpc_dec_process_siz() - see CVE-2016-9387 / bug 1396959.  Re-fixed in version 1.900.14 using the fix linked to from comment 0.

The impact of this flaw seems to be limited to triggering an assertion failure in jas_seq2d_create() function.  Failed assertion causes program to exit unexpectedly, but does not allow code execution.  As a precaution against impacts other than the known assertion failure, it may get addressed in future jasper packages in Red Hat Enterprise Linux 6 and 7.
