[PATCH 0/2] Fix Coverity untrusted loop bound bugs in jpeg.c

[Alec Brown]

In grub-core/video/readers/jpeg.c, Coverity identified an untrusted loop bound
bug. After resolving this bug, a private Coverity scan identified another
untrusted loop bound bug in a different function. Since this bug only shows up
after resolving the first bug, there isn't a CID for the second bug.

The Coverity bugs being addressed are:
CID 292450

Alec Brown (2):
      video/readers: Add artificial limit to image dimensions
      video/readers/jpeg: Check next_marker is within file size
