You know a bug is Big News when it makes National Public Radio's "All Things Considered," the network's afternoon drive-time show.

Mozilla Messaging patched nine security vulnerabilities in Thunderbird Wednesday, the first time it's plugged holes in the e-mail software since early May.

Security vulnerabilities in the iPhone's e-mail application and Safari Web browser can be used by phishers to dupe users into visiting malicious sites or by spammers to flood the phone's inbox with junk mail, a researcher warned Wednesday.

The researcher whose speculation led to an early disclosure of information about a critical flaw in the Domain Name System (DNS), the Internet's traffic cop, wasn't the first to come close to the truth, said the security expert who found the bug and organized a massive patching effort.

Mozilla Tuesday set Friday as the ship date for the first preview edition of Firefox 3.1, the fast-track update it hopes to polish off by late this year or early in 2009.
