Vulnerability Summary

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.

OpenSSL today issued a fix for a critical-turned-high-severity vulnerability that project maintainers warned about last week.  After days of speculation, infosec professionals and armchair bug hunters received more of a trick than a treat on November 1: two CVE-tagged security issues, both rated "high" severity, to patch. One flaw was earlier rated "critical," though it has now been downgraded as it will require a high degree of technical skill to exploit, if that's even possible at all aga...
