Amazon Linux 2 : openssl11 (ALAS-2023-1974)

medium Nessus Plugin ID 172155

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of openssl11 installed on the remote host is prior to 1.1.1g-12. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-1974 advisory.

 AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized 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. (CVE-2022-2097)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update openssl11' to update your system.
