Red Hat has released updated gnutls packages (e.g., gnutls-3.8.13-1.hum1) that fix this vulnerability. Users of Red Hat Hardened Images and Red Hat Enterprise Linux 9 should apply these updates promptly. Detailed update instructions are available at https://images.redhat.com/ and https://access.redhat.com/articles/11258. No alternative mitigations or workarounds are specified. Patch status is confirmed by Red Hat advisories.
Description
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.
