CVE-2007-2445

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.

Does this matter?

Lower severity and a low EPSS score (5.12%). Track it; it rarely justifies an emergency change on its own.
