This issue does not affect openjpeg2 as shipped with Red Hat Enterprise Linux 8 because the affected functionality was introduced in the current master but is absent from the shipped release.

This bug is now closed. Further updates for individual products will be reflected on the CVE page(s):

This flaw could be mitigated if OpenJPEG is not used for converting or encoding images, or untrusted input is not provided for these functions.
