game-music-emu before 0.6.1 mishandles unspecified integer values.
Integer overflow in Git before 2.7.4 allows remote attackers to execute arbitrary code via a (1) long filename or (2) many nested trees, which triggers a heap-based buffer overflow.
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.

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.

Adam Gowdiak (Security Explorations) reported that the fix for IBM JDK issue CVE-2013-5456 (bug 1027748), also known as "Issue 70", did not correctly address the problem. Applied fix only restricted access to the vulnerable package, rather then addressing the underlying problem of running untrusted code inside doPrivileged block.

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.

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,

The aestrtofflags function in archiveentry.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted mtree file.
The archivestringappend function in archivestring.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (crash) via a crafted cab files, related to "overlapping memcpy."
The lhareadfileextendedheader function in archivereadsupportformatlha.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (out-of-bounds heap) via a crafted (1) lzh or (2) lha file.
The processextra function in libarchive before 3.2.0 uses the size field and a signed number in an offset, which allows remote attackers to cause a denial of service (crash) via a crafted zip file.
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.

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 readCodersInfo function in archivereadsupportformat7zip.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted 7z file, related to the 7zfolder struct.
game-music-emu before 0.6.1 allows local users to cause a denial of service (divide by zero and process crash).
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.
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.
