Matrixssl: Security Vulnerabilities
MatrixSSL version 3.7.2 has an incorrect UTCTime date range validation in its X.509 certificate validation process resulting in some certificates have their expiration (beginning) year extended (delayed) by 100 years.

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.

An integer overflow vulnerability exists in the X509 certificate parsing functionality of InsideSecure MatrixSSL 3.8.7b. A specially crafted x509 certificate can cause a length counter to overflow, leading to a controlled out of bounds copy operation. To trigger this vulnerability, a specially crafted x509 certificate must be presented to the vulnerable client or server application when initiating secure connection
