Mozilla fixes security hole with Firefox 3.6.3

The new browser version, released just over a week after Firefox 3.6.2, fixes another critical vulnerability in the open-source browser.

Firefox

Mozilla released Firefox 3.6.3 on Thursday to close a critical security hole.

The hole, a memory corruption flaw, could have let a remote attacker run arbitrary code on a person's computer. The problem doesn't affect Firefox 3.5 or other earlier versions, Mozilla said.

Mozilla released Firefox 3.6.2 just over a week earlier, also for security reasons.

Update at 7:12 a.m. PDT: The new vulnerability was disclosed at the CanSecWest conference in March, according to a message from Mozilla security team member Dan Veditz.
