Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
