php, Python, sha3 and pysha3 are vulnerable to Denial Of Service (DoS). The vulnerability exists through the integer overflow and resultant buffer overflow in the sponge function interface due to the improper implementation of Keccak XKCP SHA-3 reference, allowing an attacker to crash the application by executing arbitrary code or eliminate expected cryptographic properties.
