CVE-2018-12889: Ccn-Lite

Critical severity, CVSS 9.8. EPSS: 1.3% chance of exploitation in the next 30 days.

An issue was discovered in CCN-lite 2.0.1. There is a heap-based buffer overflow in mkAddToRelayCacheRequest and in ccnl_populate_cache for an array lacking '\0' termination when reading a binary CCNx or NDN file. This can result in Heap Corruption. This was addressed by fixing the memory management in mkAddToRelayCacheRequest in ccn-lite-ctrl.c.
