Firefox update puts lid on Jar bug

Safe to surf

Choosing a cloud hosting partner with confidence

Mozilla released an update to its Firefox browser on Monday designed to address a trio of vulnerabilities.

Firefox 2.0.0.10 addresses a bug in the open source browser's "jar:" protocol handle, a memory corruption vulnerability, and a potential cross-site scripting hazard.

The jar: protocol handle bug was first identified in February by Mozilla's Jesse Ruderman, but efforts to smite the flaw didn't materialise until security bloggers demonstrated how the vulnerability could be abused to perform various exploits, including creating a possible means for hackers to steal a victim's Gmail contacts. Mozilla prioritised a bug fix shortly after the full impact of the bug became apparent.

Short for Java Archive, the jar: protocol is used to compress Java classes and other types of files into a single file. Unfortunately, the jar: protocol handler in Firefox (prior to the fix) failed to validate the MIME type of the contents of an archive, which would then be executed in the context of a trusted site.

The latest update is the tenth from Mozilla in little more than a year since the release of Firefox 2.0 in October 2006. ®
