Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 47.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
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.

An information leak vulnerability in rtnetlink subsystem in Linux kernel was found in "net/core/rtnetlink.c". The stack object "map" has a total size of 32 bytes. Its last 4 bytes are padding generated by compiler. These padding bytes are not initialized and sent out via nlaput().

In the marksourcechains function (net/ipv4/netfilter/iptables.c) it is possible for a user-supplied iptentry structure to have a large nextoffset field. This field is not bounds checked prior to writing a counter value at the supplied offset.

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.

A use after free vulnerability was found in pppunregisterchannel function. This is triggered when network namespace is removed while pppasync channel is still registered in it and pppunregisterchannel() tries to access its per-netns data in the defunct namespace.
An attacker who could control this memory that is being used in the defunct namespace could create a denial of service by spinlocking a CPU.
An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.

CVE request:
http://seclists.org/oss-sec/2016/q2/319
A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems. This flaw will allow attackers to alter arbitary kernel memory when unloading a kernel module. This action is usually restricted to root-priveledged users but can also be leveraged if the kernel is compiled with CONFIGUSERNS and CONFIGNETNS and the user is granted elevated priveledges.
This flaw was introduced in commit 52e804c6dfaa,

All existing releases of GraphicsMagick and ImageMagick support a file open syntax where if the first character of the file specification is a '|', then the remainder of the filename is passed to the shell for execution using the POSIX popen(3C) function. File opening is handled by an OpenBlob() function in the source file blob.c. Unlike the vulnerability described by CVE-2016-3714, this functionality is supported by the core file opening function rather than a delegates subsystem usually used to execute external programs.
