As per upstream samba advisory:
All versions of Samba from 3.5.0 to 4.2.0rc4 are vulnerable to an unexpected code execution vulnerability in the smbd file server daemon.
A malicious client could send packets that may set up the stack in such a way that the freeing of memory in a subsequent anonymous netlogon packet could allow execution of arbitrary code. This code would execute with root privileges.
Use-after-free vulnerability in Oxide allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via unspecified vectors, related to responding synchronously to permission requests.

The oxide::JavaScriptDialogManager function in oxide-qt before 1.9.1 as packaged in Ubuntu 15.04 and Ubuntu 14.04 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a crafted website.
A weakness was found in the Linux ASLR implementation. Any user able to running 32-bit applications in a x86 machine can disable the ASLR by setting the RLIMITSTACK resource to unlimited.

A race condition vulnerability was found in packetsetring that can lead to use after free on a function pointer. This vulnerability can be used to gain kernel code execution for the local attacker capable of creating AFPACKET sockets. This issue was introduced with following commit:
https://github.com/torvalds/linux/commit/f6fb8f100b807378fda19e83e5ac6828b638603a
A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation (i.e. the directory entry name being encoded by a bunch of NM entries). The process stops when the amount collected so far + the claimed amount in the current NM entry exceed 254.
However, the value returned as the total length is the sum of claimed sizes, not the actual amount collected. And that can grow pretty large - not unlimited, since you'd need to put CE entries in between to be able to get more than the maximum that could be contained in one isofs directory entry / continuation chunk and the process stops once it had encountered 32 CEs, but you can get about 8Kb easily. And that's what will be passed to readdir callback as the name length. 8Kb copytouser() from a buffer allocated by getfreepage()

In Netwide Assembler (NASM) 2.14rc0, preproc.c allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.
It was found that routing packets to too many different dsts/too fast can lead to a excessive resource consumption.
A remote attacker can use this flaw to crash the system.

The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during memory allocation, which allows context-dependent attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a long line containing wide characters that are improperly handled in a wscanf call.
Use-after-free vulnerability in Oxide before 1.5.6 and 1.6.x before 1.6.1 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code by deleting all WebContents while a RenderProcessHost instance still exists.
It was discovered that the glibc DNS resolver dereferenced a NULL pointer when processing a specific, but valid resource record type.
