CVE-2008-4108

Tools/faqwiz/move-faqwiz.sh (aka the generic FAQ wizard moving tool) in Python 2.4.5 might allow local users to overwrite arbitrary files via a symlink attack on a tmp$RANDOM.tmp temporary file. NOTE: there may not be common usage scenarios in which tmp$RANDOM.tmp is located in an untrusted directory.

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.
