"The png_handle_tRNS function in pngrutil.c in libpng before 1.0.25 and
1.2.x before 1.2.17 allows remote attackers to cause a denial of
service (application crash) via a grayscale PNG image with a bad tRNS
chunk CRC value.

This update to libpng 1.0.26 resolves this problem.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
