gnutls: gnutls: Certificate validation bypass due to oversized Subject Alternative Name

A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name SAN could cause the validation process to incorrectly fall back to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to...

gnutls: gnutls: Certificate validation bypass due to improper handling of URI and SRV SANs

A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier URI or Service SRV Subject Alternative Names SANs. This could cause the certificate validation process to incorrectly fall back to...

gnutls: gnutls: Security bypass due to incorrect name constraint handling

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...
