Our openjpeg and openjpeg2 packages have far more than this one flaw unaccounted for:
http://people.canonical.com/~ubuntu-security/cve/pkg/openjpeg.html http://people.canonical.com/~ubuntu-security/cve/pkg/openjpeg2.html (I suspect that most issues that apply to one also apply to the other; there is probably more overlap between the two packages.) Fixing just one open issue is probably not worth the time; fixing most of them would be. Finding fixes for all of them may not be feasible. Since we rely upon our community users to test updates, we really do need whoever supplies patches to have built and tested them all first. If you're in for only one release, that's still useful, and perhaps someone else would be willing to tackle the others later. Probably the 2.x.x patch can be made to apply to the 1.5.2 version we have packaged; the codebases looked very similar to me last time I reviewed both.

The vulnerability is described here (http://www.zdnet.com/article /openjpeg-zero-day-flaw-leads-to-remote-code-execution/): " Cisco Talos researchers have uncovered a severe zero-day flaw in the OpenJPEG JPEG 2000 codec which could lead to remote code execution on compromised systems. On Friday, researchers from Cisco revealed the existence of the zero- day flaw in the JPEG 2000 image file format parser implemented in OpenJPEG library. The out-of-bounds vulnerability, assigned as CVE-2016-8332, could allow an out-of-bound heap write to occur resulting in heap corruption and arbitrary code execution. OpenJPEG is an open-source JPEG 2000 codec. Written in C, the software was created to promote JPEG 2000, an image compression standard which is in popular use and is often used for tasks including embedding images within PDF documents through software including Poppler, MuPDF and Pdfium. The bug, assigned a CVSS score of 7.5, was caused by errors in parsing mcc records in the jpeg2000 file, resulting in "an erroneous read and write of adjacent heap area memory." If manipulated, these errors can lead to heap metadata process memory corruption. In a security advisory, the team said the security vulnerability can be exploited by attackers if victims open specifically crafted, malicious JPEG 2000 images. For example, if this content was within a phishing email or hosted on legitimate services such as Google Drive or Dropbox, once downloaded to their system, the path is created for attackers to execute code remotely. The vulnerability was discovered by Aleksander Nikolic from the Cisco Talos security team in OpenJpeg openjp2 version 2.1.1. Cisco Talos disclosed the vulnerability to affected vendors on 26 July, granting them time to prepare patches to fix the problem before public release. " I am filing this report as a fix for the issue doesn't seem to have yet been backported in and given the importance of the issue and the ease in exploiting it, it would be good if this is done soon.
