GNU libextractor before 1.16 loads plugins from an untrusted search path specified by the LIBEXTRACTOR_PREFIX environment variable without proper privilege checks. A local attacker can exploit this by setting LIBEXTRACTOR_PREFIX to a directory containing a malicious plugin that executes arbitrary code with elevated privileges when loaded by a setuid or setgid program.
