+# X.509 Email Address 4-byte Buffer Overflow
+
+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 the malicious certificate or for the application to
+continue certificate verification despite failure to construct a path
+to a trusted issuer. An attacker can craft a malicious email address
+to overflow four attacker-controlled bytes on the stack. This buffer
+overflow could result in a crash (causing a denial of service) or
+potentially remote code execution.
+
+Many platforms implement stack overflow protections which would mitigate
+against the risk of remote code execution. The risk may be further
+mitigated based on stack layout for any given platform/compiler.
+
+Pre-announcements of CVE-2022-3602 described this issue as CRITICAL.
+Further analysis based on some of the mitigating factors described above
+have led this to be downgraded to HIGH. Users are still encouraged to
+upgrade to a new version as soon as possible.
+
+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.
