Root Cause Analysis

The vulnerability, as described, is a null pointer dereference in the Parser::parse_binary function within the src/ELF/Parser.tcc file of the LIEF project. The provided commit 81bd5d7ea0c390563f1c4c017c9019d154802978 directly addresses this issue. The patch shows that the line binary_->sizing_info_->gnu_hash = binary_->gnu_hash_->original_size(); was not guarded by a null check for binary_->gnu_hash_. The GnuHash::parse function, called just before, can return a null pointer, which, when dereferenced in the following line, causes a segmentation fault. The fix introduces a null check, confirming the nature of the vulnerability. Therefore, the function LIEF::ELF::Parser::parse_binary is the vulnerable function that would appear in a runtime profile during exploitation.
