The nf_nat_redirect_ipv4 function in net/netfilter/nf_nat_redirect.c in the Linux kernel before 4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by sending certain IPv4 packets to an incompletely configured interface, a related issue to CVE-2003-1604.

As we inch closer to the 15th BlueHat Security Conference, we are happy to announce the lineup of speakers and topics for this event. This year will continue with a solid speaker and topic selection that engage engineers, executives, and invited guests to discuss and tackle some of the hardest problems facing the industry today.

Enhanced Mitigation Experience Toolkit (EMET) version 5.5 Beta is now available The Enhanced Mitigation Experience Toolkit (EMET) benefits enterprises and all computer users by helping to protect against security threats and breaches that can disrupt businesses and daily lives. It does this by anticipating, diverting, terminating, blocking, or otherwise invalidating the most common actions and techniques adversaries might use to compromise a computer.

One of Microsoft’s longstanding strategies toward improving software security continues to involve investing in defensive technologies that make it difficult and costly for attackers to exploit vulnerabilities. These solutions generally have a broad and long lasting impact on software security because they focus on eliminating classes of vulnerabilities or breaking the exploitation primitives that attackers rely on.

Introduction Introduction Today Microsoft released update MS15-085 to address CVE-2015-1769, an important severity security issue in Mount Manager. It affects both client and server versions, from Windows Vista to Windows 10. The goal of this blog post is to provide information on the detection guidance to help defenders detect attempts to exploit this issue.

The Thycotic Password Manager Secret Server application through 2.3 for iOS does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Today we are releasing MS15-011 & MS15-014 which harden group policy and address network access vulnerabilities that can be used to achieve remote code execution (RCE) in domain networks. The MS15-014 update addresses an issue in Group Policy update which can be used to disable client-side global SMB Signing requirements, bypassing an existing security feature built into the product.

Our Advance Notification Service (ANS) was created more than a decade ago as part of Update Tuesday to broadly communicate in advance, about the security updates being released for Microsoft products and services each month. Over the years, technology environments and customer needs have evolved, prompting us to evaluate our existing information and distribution channels.

The batadv_frag_merge_packets function in net/batman-adv/fragmentation.c in the B.A.T.M.A.N. implementation in the Linux kernel through 3.18.1 uses an incorrect length field during a calculation of an amount of memory, which allows remote attackers to cause a denial of service (mesh-node system crash) via fragmented packets.

Today Microsoft released update MS14-068 to address CVE-2014-6324, a Windows Kerberos implementation elevation of privilege vulnerability that is being exploited in-the-wild in limited, targeted attacks. The goal of this blog post is to provide additional information about the vulnerability, update priority, and detection guidance for defenders. Microsoft recommends customers apply this update to their domain controllers as quickly as possible.
