Mozilla is set to release a Firefox bugfix next week, repairing a long-standing security flaw in the software. The 22.214.171.124 update is in testing right now and should be released to the public next week. "We are giving it a couple of days to make sure that there are no issues found and we'll release it after Thanksgiving," said Mike Schroepfer, Mozilla's vice president of engineering. Mozilla is calling on the Firefox community to test the browser during a quality assurance "testday" this Friday.
The issue was first reported last February by Jesse Ruderman, but it gained widespread attention earlier this month when researcher Petko Petkov pointed out on his blog that the flaw could be used to launch a cross-site scripting attack against the Firefox browser. The flaw has to do with the fact that Firefox does not properly check files that are compressed using the .jar (Java Archive) format. Attackers could sneak malicious code into the Jar-compressed documents, which would then be run by the victim.
