RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 1 Benjamin Gilbert 2014-01-05 02:58:43 UTC 
Reassigning to openjpeg.

The OpenJPEG patch for CVE-2013-6045 disables decoding of images whose first color component has a higher resolution than subsequent components. This is a legitimate image encoding; consider, for example, YCbCr images with chroma subsampling.  This change is preventing OpenSlide from decoding certain Aperio slide files (example slide at [1]).

For example, consider p0_06.j2k from the OpenJPEG test suite [2].  With 1.3-9.el6_3:

$ j2k_to_image -i p0_06.j2k -o out.ppm

[INFO] tile 1 of 1
[INFO] - tiers-1 took 0.020997 s
[INFO] - dwt took 0.002000 s
[INFO] - tile decoded in 0.027995 s
PNM CONVERSION: Truncating component 0 from 12 bits to 8 bits
PNM CONVERSION: Truncating component 1 from 12 bits to 8 bits
PNM CONVERSION: Truncating component 2 from 12 bits to 8 bits
PNM CONVERSION: Truncating component 3 from 12 bits to 8 bits
Generated Outfile out.ppm

With 1.3-10.el6_5, the same command produces:

[INFO] tile 1 of 1
[ERROR] Error decoding tile. Component 1 contains only 33153 blocks while component 0 has 66177 blocks
ERROR -> j2k_to_image: failed to decode image!
