In Mozilla’s on going commitment to providing a safe and quality product, an updated version of Firefox (1.5.0.3) was released today. FF 1.5.0.3 previously was going to contain more fixes but due to the severity of a Denial of Service (Dos) vulnerability discovered last week this issue was addressed, fixed and put into this release. All the other fixes which were slated for the 1.5.0.3 release have been moved into the upcoming FF 1.5.0.4 release.

More information can be found in the Mozilla Firefox 1.5.0.3 Release Notes. If you have Firefox configured to Automatically Install and Download Updates (default setting) you do not need to do anything but shut-down and restart Firefox when prompted to do so. If you have the Automatic Installation disabled, go to the Help Menu and select, ‘Check For Updates…’

For those of you who may be running the older FF 1.0.8, there is no update at this time and unknown if there will be.
