Reporter

High (on shared machine, low otherwise)
Impact
Critical (local)
Products
Firefox, Mozilla Suite
Fixed in

Description

A predictable name is used for the plugin temporary directory. A malicious local user could symlink this to the victim's home directory and wait for the victim to run Firefox. When Firefox shuts down the victim's directory would be erased.

Workaround

None.
