Summary: This is an initial implementation of a Hardened Allocator based on Sanitizer Common's CombinedAllocator. It aims at mitigating heap based vulnerabilities by adding several features to the base allocator, while staying relatively fast. The following were implemented: - additional consistency checks on the allocation function parameters and on the heap chunks; - use of checksum protected chunk header, to detect corruption; - randomness to the allocator base; - delayed freelist (quarantine), to mitigate use after free and overall determinism. Additional mitigations are in the works.
