This month’s crop of updates from Microsoft includes four security bulletins, addressing 42 CVEs in Microsoft Windows, Internet Explorer, .NET Framework, and Lync Server. The update for Internet Explorer is Critical, and should be installed ASAP.

From Adobe, we get another new version of Flash, 15.0.0.152. The new version addresses memory leakage vulnerabilities that could be used to bypass memory address randomization (CVE-2014-0557), a security bypass vulnerability (CVE-2014-0554), a use-after-free vulnerability that could lead to code execution (CVE-2014-0553), memory corruption vulnerabilities that could lead to code execution (CVE-2014-0547, CVE-2014-0549, CVE-2014-0550, CVE-2014-0551, CVE-2014-0552, CVE-2014-0555), a vulnerability that could be used to bypass the same origin policy (CVE-2014-0548), and a heap buffer overflow vulnerability that could lead to code execution (CVE-2014-0556, CVE-2014-0559). Anyone still using Flash, especially within a web browser, should update immediately.

Google Chrome and Internet Explorer on Windows 8.x will be updated automatically to include the new version of Flash.
