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 9.2 Extended Update Support. The advisory addresses two vulnerabilities: a potential crash during certificate chain building/verification (CVE-2024-28835) and a Minerva side-channel information leak (CVE-2024-28834). These vulnerabilities affect the GNU Transport Layer Security library, which implements cryptographic protocols such as SSL, TLS, and DTLS. Updated gnutls packages are available to remediate these issues.

Technical Summary
The gnutls library in Red Hat Enterprise Linux 9.2 Extended Update Support is affected by two security issues. CVE-2024-28835 can cause a potential crash during chain building or verification, which may impact the stability of applications relying on gnutls. CVE-2024-28834 involves a Minerva side-channel information leak, potentially exposing sensitive cryptographic information. Red Hat has released updated gnutls packages (version 3.7.6-21.el9_2.3) that fix these vulnerabilities. The advisory rates the security impact as moderate and provides detailed package updates for multiple architectures including x86_64, aarch64, ppc64le, and s390x.
Potential Impact
The vulnerabilities could lead to application crashes during TLS certificate chain verification and potential leakage of sensitive cryptographic information through a side-channel attack. These issues may affect the confidentiality and stability of systems using the affected gnutls versions. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated gnutls packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 9.2 Extended Update Support should apply the security update as detailed in the Red Hat advisory RHSA-2024:2889. No additional mitigation steps are indicated beyond applying the official update.
