Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-2w8r-9xj7-69j5. This link is maintained to preserve external references.
Original Description
The mktemp utility in uutils coreutils fails to properly handle an empty TMPDIR environment variable. Unlike GNU mktemp, which falls back to /tmp when TMPDIR is an empty string, the uutils implementation treats the empty string as a valid path. This causes temporary files to be created in the current working directory (CWD) instead of the intended secure temporary directory. If the CWD is more permissive or accessible to other users than /tmp, it may lead to unintended information disclosure or unauthorized access to temporary data.
Affected versions
crates.io
| Package | Vulnerable | Fixed in |
|---|---|---|
| coreutils | < 0.6.0 |
0.6.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
coreutils crates.io → 0.6.0
- cargo
cargo update -p coreutils --precise 0.6.0
