CVE-ID: CVE-2022-37454

CWE-ID: CWE-190 - Integer overflow

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow within the Keccak XKCP SHA-3 reference implementation. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system or eliminate expected cryptographic properties.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
