Multiple vendors' implementations of the Secure/Multipurpose Internet Mail Extensions (S/MIME) protocol are vulnerable to multiple security issues. A remote attacker can exploit these vulnerabilities through specially crafted S/MIME email messages that include unexpected ASN.1 constructs, potentially leading to denial of service or arbitrary code execution. This risk highlights critical weaknesses in email security mechanisms and underlines the importance of staying updated and applying appropriate security patches.
