A new zero-day discovered in Internet Explorer 10 and was used in targeted attacks.
Exploit found on Android Firefox app that forces the mobile browser to download and execute a (possibly) malicious app. The exploit could also be leveraged by luring Firefox Android users with social engineering tricks.
This specific Firefox vulnerability is actually cross-platform. In fact, making the malicious code ‘work’ on all platforms is trivial as you only need to get rid of the checks looking for the Windows version.
