Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 : OpenSSL update (USN-6663-1)

info Nessus Plugin ID 191054

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6663-1 advisory.

As a security improvement, OpenSSL will now return deterministic random bytes instead of an error when detecting wrong padding in PKCS#1 v1.5 RSA to prevent its use in possible Bleichenbacher timing attacks.

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 packages.
