Untrusted search path vulnerability in python.exe in Python through 3.5.0 on Windows allows local users to gain privileges via a Trojan horse readline.pyd file in the current working directory. NOTE: the vendor says "It was determined that this is a longtime behavior of Python that cannot really be altered at this point."

Untrusted search path vulnerability in python.exe in Python through 3.5.0 on Windows allows local users to gain privileges via a Trojan horse readline.pyd file in the current working directory. NOTE: the vendor says "It was determined that this is a longtime behavior of Python that cannot really be altered at this point."

Python for Windows contains an issue with the DLL search path, which may lead to insecurely loading a DLL called readline.pyd. Takashi Yoshikawa of Mitsui Bussan Secure Directions reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.
