Adobe on Wednesday released an update for its Flash Player, the second major security release of the year for the popular software. Version 11.2 closes off two "critical" vulnerabilities in Windows, Macintosh, Linux and Solaris that were present in the prior version released in February, according to a bulletin. Android versions 2 and 3 also were updated, but 4 was not affected. If exploited, the flaws could result in a system crash or enable an attacker to take over a targeted machine. Tuesday's update also came with the option for users to request automatic updates for future Flash releases.
