In PHP versions prior to 7.4.33, 8.0.25 and 8.2.12, when using imageloadfont function in gd extension, it is possible to supply a specially crafted font file, such as if the loaded font is used with imagechar function, the read outside allocated buffer will be used. This can lead to crashes or disclosure of confidential information. The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface
