Mozilla patches old version of Firefox
Mozilla patched five vulnerabilities, three of them critical, in older editions of Firefox and in the process extended the support life of Firefox 3.0 by at least one more month. The newest Mozilla browser, Firefox 3.6, already contains the patches.
Hackers able to exploit any of the three critical bugs would be able to inject their own malware onto the machine, Mozilla noted in the accompanying advisories. "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," read the advisory dedicated to the browser engine issue.
The remaining two vulnerabilities, both rated "moderate" in Mozilla's four-step scoring system, were bugs that could be exploited in cross site scripting attacks.
One of the cross-site scripting flaws was reported by a security researcher working for browser rival Microsoft, marking the second time in two days that Microsoft experts were credited with passing along vulnerability information to a competitor. Adobe said Microsoft had found and reported a critical flaw in Reader and Acrobat.
The last time that Mozilla issued a security update for Firefox was January 5, when it fixed a flaw in the browser's upgrade mechanism and patched a bug that programmers inadvertently introduced the month before.
With the update to Firefox 3.0.18, Mozilla also extended the support lifespan of the 2008 browser beyond the January cutoff it had earlier announced. Mozilla did not immediately respond to questions about when it plans to officially retire the version. In the past, Mozilla has discontinued security updates for a browser approximately six months after the release of a newer edition. Firefox 3.5, the immediate successor to version 3.0, shipped on June 30, 2009.
