## Description

The sPLT chunk handling code (png\_set\_sPLT function in pngset.c) in libpng
1.0.6 through 1.2.12 uses a sizeof operator on the wrong data type, which
allows context-dependent attackers to cause a denial of service (crash) via
malformed sPLT chunks that trigger an out-of-bounds read.
