Summary

JPEG decoder: truncated segments are read past the image buffer, and a zero sampling factor hangs the decode

Details

The GUIX software JPEG decoder reads four kinds of marker segment without checking that each is long enough to hold what it reads. A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating. Both reproduce in the default configuration, in which GX_SOFTWARE_DECODER_SUPPORT is enabled.
