    Following the release of new versions of its open source Firefox web browser, Thunderbird email client and SeaMonkey suite, Mozilla has detailed the security fixes included in each of the updates. According to the project's Security Center page for Firefox, version 10.0 closes a total of 8 security holes in the browser, 5 of which are rated as "Critical" by Mozilla. The critical issues include an exploitable crash when processing a malformed embedded XSLT stylesheet, potential memory corruption when decoding Ogg Vorbis files, XPConnect security checks being bypassed by frame scripts, a use after free error in child nodes from nsDOMAttribute and various memory safety hazards. These vulnerabilities could be exploited remotely by an attacker to, for example, execute arbitrary code on a victim's system.
