From luke at foolishgames.com Tue Sep 30 10:44:07 2025 From: luke at foolishgames.com (Lucas Holt) Date: Tue, 30 Sep 2025 10:44:07 -0400 Subject: [Midnightbsd-users] MNBSD-2025-6 OpenSSL security vulnerability (CVE-2025-9230) Message-ID: <330cef77-a746-45af-9e6a-c3b38e332b60@foolishgames.com> A security vulnerability is present in OpenSSL in MidnightBSD 3.2.3, 4.0 current. An application trying to decrypt CMS messages encrypted using password based encryption can trigger an out-of-bounds read and write. Impact summary: This out-of-bounds read may trigger a crash which leads to Denial of Service for an application. The out-of-bounds write can cause a memory corruption which can have various consequences including a Denial of Service or Execution of attacker-supplied code. Although the consequences of a successful exploit of this vulnerability could be severe, the probability that the attacker would be able to perform it is low. Besides, password based (PWRI) encryption support in CMS messages is very rarely used. For that reason the issue was assessed as Moderate 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 this issue, as the CMS implementation is outside the OpenSSL FIPS module boundary.
