golang: crypto/tls: slow verification of certificate chains containing large RSA keys

A denial of service vulnerability was found in the Golang Go package caused by an uncontrolled resource consumption flaw. By persuading a victim to use a specially crafted certificate with large RSA keys, a remote attacker can cause a client/server to expend significant CPU time verifying...

CVE-2023-2422

A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to...

keycloak: oauth client impersonation

SUSE CVE-2009-1390

Mutt 1.5.19, when linked against 1 OpenSSL muttssl.c or 2 GnuTLS muttsslgnutls.c, allows connections when only one TLS certificate in the chain is accepted instead of verifying the entire chain, which allows remote attackers to spoof trusted servers via a man-in-the-middle attack...

SUSE CVE-2022-3786

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate...

GHSA-PJ34-FPW3-83QJ bottlerocket dependency openssl is vulnerable to read buffer overflow via X.509 verification

A read buffer overflow can be triggered in OpenSSL X.509 verification during name constraint checking. Note that this occurs after the certificate chain has been verified and would require a compromised CA. This can cause a client or agent compiled with OpenSSL to crash unexpectedly. OpenSSL has...
