Red Hat Security Advisory: gnutls security update
Red Hat has issued a moderate severity security advisory for the gnutls packages in Red Hat Enterprise Linux 9. The advisory addresses two vulnerabilities: CVE-2024-28834, a Minerva side-channel information leak, and CVE-2024-28835, a potential crash during certificate chain building and verification. These vulnerabilities affect the GNU Transport Layer Security library, which implements SSL, TLS, and DTLS protocols. An update is available to remediate these issues in Red Hat Enterprise Linux 9 across multiple architectures including x86_64, aarch64, ppc64le, and s390x.
AI Analysis
Technical Summary
The gnutls library in Red Hat Enterprise Linux 9 is affected by two security issues. CVE-2024-28834 is a side-channel information leak vulnerability related to the Minerva attack vector, potentially exposing sensitive information through side-channel analysis. CVE-2024-28835 is a flaw that can cause a crash during certificate chain building or verification, which may impact the stability of applications relying on gnutls for TLS operations. Red Hat has released updated gnutls packages that address these vulnerabilities. The advisory rates the impact as moderate and provides detailed update instructions. No CVSS score is provided in the advisory, but the severity is assessed as medium by Red Hat.
Potential Impact
The Minerva side-channel vulnerability (CVE-2024-28834) could allow attackers to infer sensitive cryptographic information through side-channel analysis, potentially weakening confidentiality guarantees. The crash vulnerability (CVE-2024-28835) could cause denial of service by crashing applications during TLS certificate chain processing. Both issues affect the security and reliability of TLS communications using gnutls on affected Red Hat Enterprise Linux 9 systems.
Mitigation Recommendations
Red Hat has released updated gnutls packages for Red Hat Enterprise Linux 9 that fix these vulnerabilities. Users should apply the security update as described in the Red Hat advisory RHSA-2024:1879 and the update article https://access.redhat.com/articles/11258 to remediate these issues. No additional mitigation steps are indicated or required beyond applying the official update.
