libjpeg-turbo 2.0.4 has a heap-based buffer over-read
in get_rgb_row() in rdppm.c via a malformed PPM input file.

CVE: CVE-2020-13790

Upstream-Status: Backport

+Subject: [PATCH] rdppm.c: Fix buf overrun caused by bad binary PPM
+
+This extends the fix in 1e81b0c3ea26f4ea8f56de05367469333de64a9f to
+include binary PPM files with maximum values < 255, thus preventing a
+malformed binary PPM input file with those specifications from
+triggering an overrun of the rescale array and potentially crashing
+cjpeg, TJBench, or any program that uses the tjLoadImage() function.
+
+Fixes #433
+
+CVE: CVE-2020-13790

++=====

++### Significant changes relative to 2.0.4:
++
++1. Fixed an issue in the PPM reader that caused a buffer overrun in cjpeg,
++TJBench, or the `tjLoadImage()` function if one of the values in a binary
++PPM/PGM input file exceeded the maximum value defined in the file's header and
++that maximum value was less than 255.  libjpeg-turbo 1.5.0 already included a
++similar fix for binary PPM/PGM files with maximum values greater than 255.
