USN-6525-1: pysha3 vulnerability

Releases

• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• pysha3 - SHA-3 (Keccak) hash implementation

Details

Nicky Mouha discovered that pysha incorrectly handled certain SHA-3
operations. An attacker could possibly use this issue to cause pysha3 to
crash, resulting in a denial of service, or possibly execute arbitrary
code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04

• python3-sha3 - 1.0.2-4.2ubuntu0.22.04.1

Ubuntu 20.04

• python3-sha3 - 1.0.2-4ubuntu0.1

In general, a standard system update will make all the necessary changes.
