  "details" : [ "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 verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address in a certificate to overflow an arbitrary number of bytes containing the `.' character (decimal 46) on the stack. This buffer overflow could result in a crash (causing a denial of service). In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects.", "A stack-based buffer overflow was found in the way OpenSSL processes X.509 certificates with a specially crafted email address field. This issue could cause a server or a client application compiled with OpenSSL to crash or possibly execute remote code when trying to process the malicious certificate." ],
  "statement" : "As per upstream, the most common situation where this can be triggered is when a server requests client authentication after a malicious client connects. A client connecting to a malicious server is also believed to be vulnerable in the same manner. Only OpenSSL versions 3.0.0 to 3.0.6 are vulnerable to this attack.",
