Title:
  Fix for CVE-2013-6045 breaks decoding of chroma-subsampled images

Status in openjpeg package in Ubuntu:
  New
Status in openjpeg package in Debian:
  Unknown

Bug description:
  The patch for CVE-2013-6045, as shipped in Ubuntu 10.04, 12.04, and 14.04, 
disables decoding of images whose first 
  color component has a higher resolution than subsequent components.  This 
occurs, for example, in YCbCr images with chroma subsampling.  This regression 
does not affect newer Ubuntu releases which ship OpenJPEG 1.5.2 or above.

  The original Debian bug report is <https://bugs.debian.org/734238>.
  Debian released an updated DSA on April 22 to correct the regression
  (https://lists.debian.org/debian-security-
  announce/2014/msg00090.html), but the fix has not propagated to
  Ubuntu.
