Ubuntu 22.04 LTS : OpenSSL vulnerability (USN-6854-1)

high Nessus Plugin ID 201069

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6854-1 advisory.

 It was discovered that OpenSSL failed to choose an appropriately short private key size when computing shared-secrets in the Diffie-Hellman Key Agreement Protocol. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libssl-dev, libssl3 and / or openssl packages.
