Microsoft today released eight security bulletins, two of them rated critical. One of the critical bulletins patches 24 vulnerabilities in Internet Explorer. Microsoft also released two separate security advisories, one updating Flash Player in IE. The June 2015 Microsoft Patch Tuesday security updates are part of the June 2015 patch Tuesday. The update patches a remote code execution bug in Windows Media Player, which Microsoft said it is not aware of exploits in the wild. The remaining bulletins are rated important by Microsoft, none of which have been publicly exploited.
