Amazon Linux 2022 : (ALAS2022-2022-147)

medium Nessus Plugin ID 166128

Language:

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-147 advisory.

 - AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of in place encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q (Affected 1.1.1-1.1.1p). (CVE-2022-2097)

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

Solution

Run 'dnf update openssl --releasever=2022.0.20221012' to update your system.
