CVE-2022-3602
Public on 2022-11-01
Modified on 2023-02-02
Description
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.
