A vulnerability was found in Linux kernel. There is an information leak in file "sound/core/timer.c" of the latest mainline Linux kernel, the stack object “tread” has a total size of 32 bytes. It contains a 8-bytes padding, which is not initialized but sent to user via copytouser(), resulting a kernel leak.
fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes.
Destroy of network interface with huge number of ipv4 addresses keeps rtnllock for a very long time (up to hour). It blocks many network related operations, including for example creation of new incoming ssh connections.
The problem is especially important for containers, container owner have enough permission to enable this trigger and then can block network access on whole host node.

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PRSETTSC prctl calls within a modified copy of QEMU.

A vulnerability was found in the usbnet Linux kernel driver.
The bug allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have other impact by inserting a USB device with an invalid USB descriptor.

A flaw was found in in the Linux kernel's USB device management code which could cause a kernel panic when a device which required atiremote2 kernel module. The kernel would panic causing null pointer dereference attempting to access a non existent interface descriptor. The atiremote2 driver assumes that there will be at least two interface-descriptors with associated endpoint-descriptors.

Use-after-free vulnerability in the SetBreaks function in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a document containing crafted text in conjunction with a Cascading Style Sheets (CSS) token sequence containing properties related to vertical text.
Heap-based buffer overflow in the SVGTextFrame class in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 allows remote attackers to execute arbitrary code via crafted SVG graphics data in conjunction with a crafted Cascading Style Sheets (CSS) token sequence.
The tmreclaimthread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tmreclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application.
Google Chrome before 42.0.2311.90 does not properly consider the interaction of page navigation with the handling of touch events and gesture events, which allows remote attackers to trigger unintended UI actions via a crafted web site that conducts a "tapjacking" attack.
Unspecified vulnerability in Oracle Java SE 6u85, 7u72, and 8u25 allows remote attackers to affect confidentiality via unknown vectors related to Libraries.
Unspecified vulnerability in Oracle Java SE 5.0u75, 6u85, 7u72, and 8u25; Java SE Embedded 7u71 and 8u6; and JRockit R27.8.4 and R28.3.4 allows local users to affect integrity and availability via unknown vectors related to Hotspot.
It was found that systemd fails an assertion in managerinvokenotifymessage() when a zero-length message is received over its notification socket, causing it to no longer perform it's expected functionality. This issue was assigned CVE-2016-7795 and is tracked via bug 1380286. Upstream bug report is:
https://github.com/systemd/systemd/issues/4234
Older systemd versions either don't include the assert that is triggered in managerinvokenotifymessage(), or have managerprocessnotifyfd() function return error before calling managerinvokenotifymessage(). That error return still causes systemd to exit its main loop and freeze its execution in a similar way it's done in newer versions after failed assertion.
https://github.com/systemd/systemd/issues/4234#issuecomment-250441246
The managerinvokenotifymessage() function with assert was introduced in version v209:
https://github.com/systemd/systemd/commit/5ba6985b6c8ef85a8bcfeb1b65239c863436e75b#diff-ab78220e12703ee63fa1e6a2caa16bebR1319
However, the assertion was not reachable before the error return was removed in v219:
https://github.com/systemd/systemd/commit/d875aa8ce10b458dc218c0d98f4a82c8904d6d03
The systemd versions in Red Hat Enterprise Linux 7.0 and 7.1 are based on upstream v208, but include managerinvokenotifymessage() added via a separate backported patch. The assertion is not reachable, so those versions are affected by CVE-2016-7796, but not affected by CVE-2016-7795. Red Hat Enterprise Linux 7.2 rebased systemd to version v219. Therefore, those packages are no longer affected by CVE-2016-7796, but are now affected by CVE-2016-7795.
The tls.checkServerIdentity function in Node.js 0.10.x before 0.10.47, 0.12.x before 0.12.16, 4.x before 4.6.0, and 6.x before 6.7.0 does not properly handle wildcards in name fields of X.509 certificates, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.
An unspecified low-severity Node.js HTTP processing vulnerability was found and will be fixed in latest update. Details are currently embargoed until new releases are available.
