CVSS: 7.5EPSS: 10%CPEs: 9EXPL: 4CVE-2022-3602 – X.509 Email Address 4-byte Buffer Overflow
https://notcve.org/view.php?id=CVE-2022-3602
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. • https://github.com/colmmacc/CVE-2022-3602 https://github.com/eatscrayon/CVE-2022-3602-poc https://github.com/corelight/CVE-2022-3602 https://github.com/cybersecurityworks553/CVE-2022-3602-and-CVE-2022-3786 http://packetstormsecurity.com/files/169687/OpenSSL-Security-Advisory-20221101.html http://www.openwall.com/lists/oss-security/2022/11/01/15 http://www.openwall.com/lists/oss-security/2022/11/01/16 http://www.openwall.com/lists/oss-security/2022/11/01/17 http://www&# • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
