CVE-2026-3832: Incorrect Behavior Order: Early Validation
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
AI Analysis
Technical Summary
A logic error in GnuTLS's handling of multi-record OCSP responses can cause clients with OCSP verification enabled to accept revoked server certificates during TLS handshakes. This vulnerability (CVE-2026-3832) allows a remote attacker to present a crafted OCSP response to bypass certificate revocation checks, potentially compromising trust. The issue affects Red Hat Hardened Images and is addressed in updated RPM packages (gnutls-3.8.13-1.hum1 and related). The vendor advisory references these updates but does not explicitly confirm a dedicated fix for this CVE alone. The CVSS 3.7 score reflects low severity due to the complexity and conditions required for exploitation. No exploits in the wild are known at this time.
Potential Impact
A remote attacker could exploit this vulnerability by sending a specially crafted OCSP response during a TLS handshake, causing a client with OCSP verification enabled to incorrectly accept a revoked server certificate. This may lead to a compromise of trust in the TLS connection. The impact is limited to confidentiality (partial, as indicated by CVSS vector) with no direct integrity or availability impact reported. The overall severity is low.
Mitigation Recommendations
Red Hat has released updated gnutls RPM packages (version 3.8.13-1.hum1) for Red Hat Hardened Images that include fixes addressing this and other vulnerabilities. Users should apply these updates as per Red Hat's guidance at https://images.redhat.com/. Patch status for this specific CVE is not explicitly confirmed in the advisory, but the presence of updated packages indicates remediation is available. No additional mitigation steps are specified by the vendor.
