Security Fix(es): * openssl: OpenSSL: Arbitrary code execution due to out-of-bounds write in PKCS#12 processing (CVE-2025-69419) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The compat-openssl11 package in Red Hat Enterprise Linux 9 contains libraries from OpenSSL version 1.1.1. A vulnerability identified as CVE-2025-69419 involves an out-of-bounds write during PKCS#12 processing, which can lead to arbitrary code execution. Red Hat has issued a security advisory (RHSA-2026:19187) describing this issue and providing updated packages to remediate it. The advisory covers multiple architectures including x86_64, s390x, ppc64le, and aarch64. The update is rated as moderate severity by Red Hat. No CVSS score is provided in the advisory, but the impact is significant enough to warrant a security update. There are no known exploits in the wild at this time.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on affected systems due to an out-of-bounds write in the PKCS#12 processing code of OpenSSL 1.1.1 libraries. This could compromise system integrity and security. The vulnerability affects the compat-openssl11 package used for compatibility with previous OpenSSL releases in Red Hat Enterprise Linux 9. No known active exploits have been reported.
Mitigation Recommendations
Red Hat has released updated packages for compat-openssl11 that address CVE-2025-69419. Users of affected Red Hat Enterprise Linux 9 versions should apply the security update as described in Red Hat advisory RHSA-2026:19187. Detailed instructions for applying the update are available at https://access.redhat.com/articles/11258. Since this is an official fix, applying the update fully mitigates the vulnerability. No additional mitigation steps are required beyond applying the vendor-provided update.
