The SPICE (aka spice-xpi) plug-in 2.2 for Firefox allows local users to overwrite arbitrary files via a symlink attack on an unspecified log 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

Name Vendor Start Version End Version
Red Hat Enterprise Linux 5 RedHat spice-xpi-0:2.2-2.3.el5_5 *

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.
