ID CVE-2017-2782
Summary 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

  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
