FreeBSD : firefox -- denial of service vulnerability (e2476979-da74-11da-a67b-0013d4a4a40e)

Medium Nessus Plugin ID 21523


The remote FreeBSD host is missing one or more security-related updates.


A Mozilla Foundation Security Advisory reports for deleted object reference when designMode='on'

Martijn Wargers and Nick Mott each described crashes that were discovered to ultimately stem from the same root cause : attempting to use a deleted controller context when designMode was turned on. This generally results in crashing the browser, but in theory references to deleted objects can be abused to run malicious code.

'splices' reported the same crash at the fan site MozillaZine and on Bugtraq, incorrectly describing it as a buffer overflow.


Update the affected packages.
