TITLE

InsideSecure MatrixSSL Buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2017-005021

DESCRIPTION

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. InsideSecure MatrixSSL Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Inside Secure MatrixSSL is an IoT application toolkit from the French company Inside Secure, which can implement TLS and DTLS in a modular way. MatrixSSL is prone to multiple buffer-overflow vulnerabilities. Failed exploit attempts will result in denial-of-service conditions. MatrixSSL 3.8.7b is vulnerable; other versions may also be affected
