Mozilla Patches Critical Firefox Security Patch

Just a few days after issuing more than a dozen security updates, many of them critical, the foundation that published the popular Firefox web browser issues a patch to fix its patch.

Just a few days after issuing more than a dozen security updates, many of them critical, the foundation that published the popular Firefox web browser issues a patch to fix its patch.According to Mozilla Foundation Security Advisory 2010-48, Mozilla developer Daniel Holbert identified that the fix to the plugin parameter array crash that was fixed in Firefox 3.6.7 caused a crash that showed indications of memory corruption. "In certain circumstances, properties in the plugin instance's parameter array could be freed prematurely leaving a dangling pointer that the plugin could execute, potentially calling into attacker-controlled memory," the security update states.

The update came several days after Mozilla Foundation issued 14 advisories with eight listed as "critical," two as "high," and four as "moderate." Critical vulnerabilities are especially troublesome as Mozilla defines them as a vulnerability that: can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.

Other than avoiding untrustworthy web sites, being careful of what files are downloaded to the system, and not running software of unknown origin, keeping one's web browser up to date is an important part of keeping a system secure.

Firefox users can see if they're running the latest, and presumably the safest, version of Firefox by selecting "Check for updates" within the Help pull-down.

For my security, technology, and business observations throughout the day, fine me on Twitter.
