==== Bug Description ====
Not Patched
When inserting NaN with a parameter as an argument into parseFloat(), we can overflow the tiny buffer created by parseFloat().

==== Patched ====
Patched on PS3 FW 4.83. Remains exploitable on higher firmwares by installing old WebKit sprx files in hybrid PUP.
 
=== WebKit CSS font face source type confusion leading to read primitive ===
 
==== Credits ====
TODO
 
==== Bug Description ====
While parsing the source of a CSS font face, CSSParser::parseFontFaceSrc() assumes the value given is a string, but if we insert a specific double value into an exploitable function like insert() or format(), we can leak the memory via an overlap between two variables.

=== Renesas verify function works on 4 byte values in All renesas/nec SysCon chips ===


All NEC/Renesas syscon chips have their verify function working for a 4 byte array but 256 byte size, increasing the probability of finding the correct bytes as opposed to the intended 256 bytes.

=== (Universal) Renesas checksum function works on 256 byte values (ALL SYSCON CHIPS, stock, psp, vita, ps3, ps4) ===


Renesas checksum feature works on 256 byte values instead of the intended block size, which means glitching could be done in a narrower margin, making the efforts a lot easier. it is also possible to identify 256 byte constants contiguous to each other by their checksums.
