While Mozilla is busily developing its next-generation Firefox 3 open source Web browser, work continues to improve stability and security with the current Firefox 2.x.
A case in point is the new Firefox 220.127.116.11 release, which is accompanied by no less than six Mozilla Foundation Security Advisories -- two of them critical.
The second critical bug fix by Mozilla in the latest release relates to memory corruption.
"Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products," Mozilla said in its advisory. "Some of these crashes showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code."
The new release also addresses a unique spoofing vulnerability that could potentially be used by an attacker in a phishing exploit.
