Description

The libpng project reports:

pngcheck versions 3.0.0 and earlier have a pair of buffer-overrun

bugs related to the sPLT and PPLT chunks (the latter is a MNG-only

chunk, but it gets noticed even in PNG files if the -s option is used).

Both bugs are fixed in version 3.0.1, released on 24 January 2021.

Again, while all known vulnerabilities are fixed in this version,

the code is quite crufty, so it would be safest to assume there are

still some problems hidden in there. As always, use at your own risk.
