CVE-2008-5380

gpsdrive (aka gpsdrive-scripts) 2.09 allows local users to overwrite arbitrary files via a symlink attack on an (a) /tmp/geo#####, a (b) /tmp/geocaching.loc, a (c) /tmp/geo#####., or a (d) /tmp/geo. temporary file, related to the (1) geo-code and (2) geo-nearest scripts, different vectors than CVE-2008-4959.

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.

Affected Software

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.
