GitHub Vulnerability Alerts

CVE-2023-49797

Impact

A PyInstaller built application, elevated as a privileged process, may be tricked by an unprivileged attacker into deleting files the unprivileged user does not otherwise have access to.

A user is affected if all the following are satisfied:

  • The user runs an application containing either matplotlib or win32com.
  • The application is ran as administrator (or at least a user with higher privileges than the attacker).
  • The user's temporary directory is not locked to that specific user (most likely due to TMP/TEMP environment variables pointing to an unprotected, arbitrary, non default location).
  • Either:
    • The attacker is able to very carefully time the replacement of a temporary file with a symlink. This switch must occur exactly between shutil.rmtree()'s builtin symlink check and the deletion itself
    • The application was built with Python 3.7.x or earlier which has no protection against Directory Junctions links

Patches

The vulnerability has been addressed in https://github.com/pyinstaller/pyinstaller/pull/7827 which corresponds to pyinstaller >= 5.13.1

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

No workaround, although the attack complexity becomes much higher if the application is built with Python >= 3.8.0.

CVE-2025-59042

Impact

Due to a special entry being appended to sys.path during the bootstrap process of a PyInstaller-frozen application, and due to the bootstrap script attempting to load an optional module for bytecode decryption while this entry is still present in sys.path, an application built with PyInstaller < 6.0.0 may be tricked by an unprivileged attacker into executing arbitrary python code when all of the following conditions are met:

  1. Application is built with PyInstaller < 6.0.0; both onedir and onefile mode are affected.
  2. Optional bytecode encryption code feature was not enabled during the application build.
  3. The attacker can create files/directories in the same directory where the executable is located.
  4. The filesystem supports creation of files/directories that contain ? in their name (i.e., non-Windows systems).
  5. The attacker is able to determine the offset at which the PYZ archive is embedded in the executable.

The attacker can create a directory (or a zip archive) next to the executable, with the name that matches the format used by PyInstaller's bootloader to transmit information about the location of PYZ archive to the bootstrap script. If this directory (or zip archive) contains a python module whose name matches the name used by the optional bytecode encryption feature, this module will be loaded and executed by the bootstrap script (in the absence of the real, built-in module that is available when the bytecode-encryption feature is enabled). This results in arbitrary code execution that requires no modification of the executable itself.

If the executable is running with elevated privileges (for example, due to having the setuid bit set), the code in the injected module is also executed with the said elevated privileges, resulting in a local privilege escalation.

Patches

PyInstaller 6.0.0 (f5adf291c8b832d5aff7632844f7e3ddf7ad4923) removed support for bytecode encryption; this effectively removes the described attack vector, due to the bootstrap script not attempting to load the optional module for bytecode-decryption anymore.

PyInstaller 6.10.0 (cfd60b510f95f92cb81fc42735c399bb781a4739) reworked the bootstrap process to avoid (ab)using sys.path for transmitting location of the PYZ archive, which further eliminates the possibility of described injection procedure.

Workarounds

If upgrading PyInstaller is no feasible, this issue can be worked around by ensuring proper permissions on directories containing security-sensitive executables (i.e., executables with setuid bit set) should mitigate the issue.
