Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service (crash) via a large L2 table in a QCOW version 1 image.

Today, we announced the availability of SSL 3.0 fallback warnings in Internet Explorer (IE) 11. For more information please visit the IE blog. We have also published an update on the status of the changes we have made to our Azure offerings in response to the SSL 3.0 vulnerability. For more information please visit the Azure blog.

Unspecified vulnerability in Oracle Java SE 6u81, 7u67, and 8u20 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Deployment, a different vulnerability than CVE-2014-6493, CVE-2014-6503, and CVE-2014-6532.

Unspecified vulnerability in Oracle MySQL Server 5.5.39 and earlier and 5.6.20 and earlier allows remote authenticated users to affect availability via vectors related to SERVER:OPTIMIZER.

The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.

Today, as part of Update Tuesday, we released eight securityupdates – three rated Critical and five rated Important - to address 24 Common Vulnerabilities & Exposures (CVEs) in Windows, Office, .NET Framework, .ASP.NET, and Internet Explorer (IE). We encourage you to apply all of these updates, but for those who need to prioritize deployment planning, we recommend focusing on the Critical updates first.

The Smart Call Home (SCH) implementation in Cisco ASA Software 8.2 before 8.2(5.50), 8.4 before 8.4(7.15), 8.6 before 8.6(1.14), 8.7 before 8.7(1.13), 9.0 before 9.0(4.8), and 9.1 before 9.1(5.1) allows remote attackers to bypass certificate validation via an arbitrary VeriSign certificate, aka Bug ID CSCun10916.

The SSL VPN implementation in Cisco Adaptive Security Appliance (ASA) Software 9.2(.2.4) and earlier does not properly manage session information during creation of a SharePoint handler, which allows remote authenticated users to overwrite arbitrary RAMFS cache files or inject Lua programs, and consequently cause a denial of service (portal outage or system reload), via crafted HTTP requests, aka Bug ID CSCup54208.

Today, we are excited to announce the general availability of the Enhanced Mitigation Experience Toolkit (EMET) 5.0. As many of you already know, EMET is a free tool, designed to help customers with their defense in depth strategies against cyberattacks, by helping detect and block exploitation techniques that are commonly used to exploit memory corruption vulnerabilities.

Unspecified vulnerability in Oracle Java SE 6u75, 7u60, and 8u5 allows remote attackers to affect integrity via unknown vectors related to Deployment.
