high Nessus Plugin ID 270550

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 ALAS2-2025-3034 advisory.

Issue summary: An application trying to decrypt CMS messages encrypted usingpassword based encryption can trigger an out-of-bounds read and write.

Impact summary: This out-of-bounds read may trigger a crash which leads toDenial of Service for an application. The out-of-bounds write can causea memory corruption which can have various consequences includinga Denial of Service or Execution of attacker-supplied code.

Although the consequences of a successful exploit of this vulnerabilitycould be severe, the probability that the attacker would be able toperform it is low. Besides, password based (PWRI) encryption support in CMSmessages is very rarely used. For that reason the issue was assessed asModerate severity according to our Security Policy.

The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by thisissue, as the CMS implementation is outside the OpenSSL FIPS moduleboundary. (CVE-2025-9230)

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' or or 'yum update --advisory ALAS2-2025-3034' to update your system.
