An exploitable heap buffer overflow vulnerability exists in the X509 certificate parsing functionality of InsideSecure MatrixSSL 3.8.7b. A specially crafted x509 certificate can cause a buffer overflow on the heap resulting in remote code execution. To trigger this vulnerability, a specially crafted x509 certificate must be presented to the vulnerable client or server application when initiating secure connection.

Security readout for executives and security teams

CVE-2017-2781 is a remote code execution risk in Inside Secure MatrixSSL 3.8.7b. A malicious X509 certificate presented during a secure connection can overflow heap memory. Business impact depends on whether this specific TLS library version is embedded in your products or services. Organizations are exposed only where applications, appliances, firmware, or services use Inside Secure MatrixSSL 3.8.7b and parse peer X509 certificates during TLS connection setup. Treat as high priority for any product or service confirmed to use MatrixSSL 3.8.7b. The risk is remote code execution, but exposure is specific and the attack complexity is rated high. Mitigation focus: Inventory software and firmware for Inside Secure MatrixSSL 3.8.7b usage.; Check Inside Secure or product-vendor guidance for a fixed or supported MatrixSSL release.; Prioritize remediation for internet-facing or partner-facing TLS clients and servers..
