Amazon Linux 2 : openssl (ALAS-2024-2479)

medium Nessus Plugin ID 191518

Language:

Synopsis

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

Description

The version of openssl installed on the remote host is prior to 1.0.2k-24. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2479 advisory.

 Processing a maliciously formatted PKCS12 file may lead OpenSSL to crash leading to a potential Denial of Service attack

 The package openssl098e is provided purely for binary compatibility with older Amazon Linux versions. It does not receive security updates. (CVE-2024-0727)

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 openssl' to update your system.
