Description

A new buffer overrun vulnerability has been detected in OpenSSL 3.x

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. The risk may be further mitigated based on stack layout for any given platform/compiler.

All current versions of Desktop and Laptop Option (DLO) Agent (up to 9.8) use OpenSSL 1.x and are not impacted by this CVE-2022-3602 vulnerability.
