GitHub Vulnerability Alerts

CVE-2023-38497

The Rust Security Response WG was notified that Cargo did not respect the umask when extracting crate archives on UNIX-like systems. If the user downloaded a crate containing files writeable by any local user, another local user could exploit this to change the source code compiled and executed by the current user.

This vulnerability has been assigned CVE-2023-38497.

Overview

In UNIX-like systems, each file has three sets of permissions: for the user owning the file, for the group owning the file, and for all other local users. The "umask" is configured on most systems to limit those permissions during file creation, removing dangerous ones. For example, the default umask on macOS and most Linux distributions only allow the user owning a file to write to it, preventing the group owning it or other local users from doing the same.

When a dependency is downloaded by Cargo, its source code has to be extracted on disk to allow the Rust compiler to read as part of the build. To improve performance, this extraction only happens the first time a dependency is used, caching the pre-extracted files for future invocations.

Unfortunately, it was discovered that Cargo did not respect the umask during extraction, and propagated the permissions stored in the crate archive as-is. If an archive contained files writeable by any user on the system (and the system configuration didn't prevent writes through other security measures), another local user on the system could replace or tweak the source code of a dependency, potentially achieving code execution the next time the project is compiled.

Affected Versions

All Rust versions before 1.71.1 on UNIX-like systems (like macOS and Linux) are affected. Note that additional system-dependent security measures configured on the local system might prevent the vulnerability from being exploited.

Users on Windows and other non-UNIX-like systems are not affected.

Mitigations

We recommend all users to update to Rust 1.71.1, which will be released later today, as it fixes the vulnerability by respecting the umask when extracting crate archives. If you build your own toolchain, patches for 1.71.0 source tarballs are available here.

To prevent existing cached extractions from being exploitable, the Cargo binary included in Rust 1.71.1 or later will purge the caches it tries to access if they were generated by older Cargo versions.

If you cannot update to Rust 1.71.1, we recommend configuring your system to prevent other local users from accessing the Cargo directory, usually located in ~/.cargo:

chmod go= ~/.cargo
