"The remote Microsoft SQL Server installation is affected by multiple
vulnerabilities :

  - A privilege escalation vulnerability exists due to the
    casting of pointers to an incorrect class. An
    authenticated, remote attacker can exploit this, via a
    specially crafted SQL query, to gain elevated
    privileges. (CVE-2015-1761)

  - A remote code execution vulnerability exists due to
    incorrect handling of internal function calls to
    uninitialized memory. An attacker can exploit this, via
    a specially crafted SQL query on an affected SQL server
    that has special permission settings (such as VIEW
    SERVER STATE) turned on, to execute arbitrary code.
    (CVE-2015-1762)

  - A remote code execution vulnerability exists due to
    incorrect handling of internal function calls to
    uninitialized memory. An authenticated, remote attacker
    can exploit this, via a specially crafted SQL query
    designed to execute a virtual function from a wrong
    address, to execute arbitrary code. (CVE-2015-1763)");
