The IES parser in Cycles would lead to heap buffer overflow error when non-supported or invalid data is provided to it. The error was caused by the way how stirng is copied to vector skipping the last null-terminator. Later C-style string utilities are used for parsing, and they expect the data to be null-terminated. It is unclear why data needs to be stored as vector: storing it as string simplifies initialization. Easiest to reproduce the issue is to use Blender build with address sanitizer enabled.
