Mozilla Firefox 27 arrives

Mozilla has released Firefox 27, which comes with as many as 13 security advisories attached, and delivers an improved performance. To sum it up, the debut open source Firefox release of 2014 comes with security and performance that is notches higher than its predecessor.

Notably, four of the security advisories have been ranked as being ‘critical'. At least one of the critical updates is for a group of vulnerabilities labelled ‘Miscellaneous memory safety hazards'. PC maker Hewlett-Packard had earlier reported concerns over a use-after-free memory error that enables attackers to launch an arbitrary attack by utilising legitimate memory space. Mozilla Firefox 27 comes with a fix for the problem, while also providing a fix for a download dialogue box window issue that could potentially enable a spoofing attack.

At the same time, the release offers a fix to an issue rated as having low impact that could enable an attacker to reset a user's profile. And it now includes default support for the Transport Layer Security (TLS) 1.2 specification.
