Background
The compat-openssl11 package is a compatibility layer for the OpenSSL toolkit, which is essential for secure communications between machines. This package includes libraries from the OpenSSL 1.1.1 version, enabling applications that depend on older OpenSSL versions to function correctly. However, this compatibility can also expose systems to vulnerabilities present in older versions.
Vulnerability Detail
The vulnerability identified as CVE-2025-69419 is an out-of-bounds write issue in the PKCS#12 processing of the OpenSSL toolkit. This flaw allows an attacker to execute arbitrary code on the affected system, potentially leading to unauthorized access, data breaches, or system compromise. The vulnerability arises from improper handling of input data, which can be exploited by crafting malicious PKCS#12 files.
How To Fix
Minimum fixed version
1:1.1.1k-5.el9_7.1
This is the first release that contains the fix.
