src/unit_test.c in gpsdrive (aka gpsdrive-scripts) 2.10~pre4 might allow local users to overwrite arbitrary files via a symlink attack on the /tmp/gpsdrive-unit-test/proc temporary file, a different vector than CVE-2008-4959 and CVE-2008-5380.
Weakness
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Potential Mitigations
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
