Comment 5 Tomas Hoger 2020-05-04 20:41:50 UTC

The reproducer triggers assertion failure abort in jpc_dec_process_sot() known as CVE-2017-13745 (bug 1488958) that remains unfixed upstream.  The reported leak is minor, and it does not make much sense to consider it as a security problem while the abort problem is not fixed.  Not currently planning to address this issue in Red Hat products.
