[Midnightbsd-users] MNBSD-2025-6 OpenSSL security vulnerability (CVE-2025-9230)

[Lucas Holt]

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.
