SUSE CVE-2026-91767

phpopensslmatcheswildcardname in ext/openssl/xpssl.c underflows the length argument passed to memchr when a TLS server certificate presents a wildcard name whose literal characters are together longer than the hostname being verified. A malicious server presenting such a certificate makes the PHP...

SUSE CVE-2026-91769

PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name. RFC 6125 requires the CN to be ignored once the certificate presents any service identity, so a certificate carrying a non-matching DNS SAN w...

CVE-2026-73581

A flaw was found in Apache Tomcat. Both the OpenSSL and OpenSSL-FFM Transport Layer Security TLS implementations fail to properly check Certificate Revocation Lists CRLs when a certificate uses a keystore. This oversight could allow an attacker to use a revoked certificate, potentially leading to...
