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.

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.

The SSL VPN implementation in Cisco Adaptive Security Appliance (ASA) Software 9.3(.2) and earlier does not properly allocate memory blocks during HTTP packet handling, which allows remote attackers to cause a denial of service (memory consumption) via crafted packets, aka Bug ID CSCuq68888.

cURL and libcurl before 7.38.0 allow remote attackers to bypass the Same Origin Policy and set cookies for arbitrary sites by setting a cookie for a top-level domain.

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.

The futex_wait function in kernel/futex.c in the Linux kernel before 2.6.37 does not properly maintain a certain reference count during requeue operations, which allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that triggers a zero count.

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly consider the possibility of kmalloc failure, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a long unencrypted auth ticket.

arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call.

Cross-site scripting (XSS) vulnerability in user/help/html/index.php in Fonality trixbox allows remote attackers to inject arbitrary web script or HTML via the id_nodo parameter.

Today, we are updating the Certificate Trust List (CTL) for all supported releases of Microsoft Windows to remove the trust of mis-issued third-party digital certificates. These certificates could be used to spoof content and perform phishing or man-in-the-middle attacks against web properties. With this update, most customers will be automatically protected against this issue and will not need to take any action.
