New threats show browser vulnerabilities don't play favorites

“Browser vulnerabilities are making the rounds this week, as different threats have surfaced for Mozilla, Firefox, Netscape, and Internet Explorer. In this edition of the IT Locksmith, learn more about these various threats, find out how you can best protect your organization from these vulnerabilities, and see what else has recently surfaced in the security world.

New vulnerabilities are haunting Mozilla, Firefox, and Netscape browsers, while different threats have surfaced in Outlook and Internet Explorer. Meanwhile, IM and P2P threats surge.

Secunia has reported, and Mozilla has confirmed, an information disclosure vulnerability in the Firefox browser—including the latest update (version 1.0.2), which is only a few weeks old (released March 21).

Mozilla released the new release candidate (also designated 1.0.3) the very next day. Be forewarned that this release candidate 1.0.3, and probably the eventual release version as well, will likely cause problems with a number of extensions.

• Netscape
