  - A binary planting vulnerability exists due to improper path or signature validation. An authenticated, local

    uses untrusted input when calculating or using an array index,

    a pointer that it expects to be valid, but is NULL, which may
    lead to code execution, denial of service or escalation of

disclosure vulnerabilities. See the vendor advisory for details.");
