Ghidra < 12.1 - Path Traversal via .gnu_debuglink in DWARF External Debug File Resolution
Get instant alerts when new vulnerabilities affect ghidra - before attackers find them.
Ghidra before 12.1 contains a path traversal vulnerability in SameDirDebugInfoProvider that fails to validate filenames from ELF binary .gnu_debuglink sections before constructing file paths. Attackers can craft malicious ELF binaries with traversal sequences to probe filesystem existence and leak CRC32 hashes of arbitrary files during automatic DWARF analysis.
