OpenSSL: Schwachstelle ermöglicht Codeausführung, Datenmanipulation, Offenlegung von Informationen und Dos
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library. Security Fix(es): * openssl: Use After Free with SSL_free_buffers (CVE-2024-4741) * openssl: Heap Use-After-Free in OpenSSL PKCS7_verify() (CVE-2026-45447) 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
Two use-after-free vulnerabilities have been identified in OpenSSL: CVE-2024-4741 involves SSL_free_buffers, and CVE-2026-45447 involves heap use-after-free in PKCS7_verify(). These flaws could allow attackers to cause memory corruption. Red Hat Product Security has issued an important security advisory (RHSA-2026:26275) providing updated OpenSSL packages for Red Hat Enterprise Linux 8 and related variants to address these issues. The advisory references the CVEs and provides links to updated packages and remediation instructions.
Potential Impact
The vulnerabilities could lead to use-after-free conditions causing memory corruption, which may result in application crashes or potentially enable further exploitation depending on the context of use. The advisory rates the security impact as Important (high severity). There are no known exploits in the wild at the time of the advisory.
Mitigation Recommendations
Red Hat has released updated OpenSSL packages that fix these vulnerabilities. Users should apply the security update provided in RHSA-2026:26275 for their respective Red Hat Enterprise Linux 8 variants. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigations are specified or required beyond applying the official patch.
