CriticalCVSS 9.8
Published: Updated: Translated: NVD NIST

Exploitation Probability (EPSS)

Very high risk
5.77%

93th percentile - higher than 93% of all known CVEs

Summary

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.

Risk Assessment

Remote code execution or weakening of cryptographic properties is possible, undermining trust in the security mechanisms in use. Organizations using this SHA-3 implementation are exposed to compromise.

Recommendation

Update the Keccak XKCP library to a version containing commit fdc6fef or later. Verify that deployed systems do not use the vulnerable version.
