Issue Overview:

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. (CVE-2022-37454)

Affected Packages:

python38

Issue Correction:
Run yum update python38 to update your system.
