CVE-2007-5718

vobcopy 0.5.14 allows local users to append data to an arbitrary file, or create an arbitrary new file, via a symlink attack on the (1) /tmp/vobcopy.bla or (2) /tmp/vobcopy_0.5.14.log temporary file.

Weakness

The software 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.
