More Mac security updates to extinguish Flashback trojan

To further stop the spread of the Flashback trojan, Apple on Monday released two security updates for Mac OS X 10.5 (Leopard). The updates target those users who have not upgraded to more recent versions of the platform, which already have been fixed for the Java vulnerability that Flashback exploits. While one of the new updates disables Safari's Java plug-in, the other addresses Flashback itself, scanning a users' hard drive for variants of the malware and removing them. The updates can be applied through the built-in Software Update feature. In light of the outbreak, rumors have flown that Apple has sought security help from Kaspersky Lab, but the Russian anti-virus vendor has denied this.
