Cross-site scripting (XSS) vulnerability in the navpath function in lib/viewvc.py in ViewVC before 1.0.14 and 1.1.x before 1.1.26 allows remote attackers to inject arbitrary web script or HTML via the navdata name.
An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited.
Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks.
A memory allocation failure was discovered in GraphicsMagick in MagickRealloc in memory.c

Bookkeeping errors when extending the read-ahead buffer when trying to identify an mtree archive could lead libarchive to significantly overcalculate the size of the line being read, resulting in heap out-of-bounds reads or a crash.

Read out-of-bounds in gitoidnfmt: https://github.com/libgit2/libgit2/issues/3936
CVE-2016-8569
DoS using a null pointer dereference in gitcommitmessage: https://github.com/libgit2/libgit2/issues/3937
Proposed patch:
https://github.com/libgit2/libgit2/pull/3956
The gitoidnfmt function in commit.c in libgit2 before 0.24.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via a cat-file command with a crafted object file.
parsetagx.c in w3m before 0.5.3+git20161009 does not properly initialize values, which allows remote attackers to crash the application via a crafted html file, related to a <i> tag.
The HTMLtagproc1 function in file.c in w3m before 0.5.3+git20161009 does not properly initialize values, which allows remote attackers to crash the application via a crafted html file, related to <dd> tags.
A new exploitation technique called key reinstallation attacks used to break Wi-Fi handshakes that negotiate session keys was discovered. These attacks target the Wi-Fi/WPA2 standard. An adversary can trick a client or Access Point (AP) into reinstalling an already-in use pairwise key in 4-way handshake. While reinstalling the already in-use key, the associated packet number (sometimes also called nonce) and receive replay counter is reset. This causes nonce reuse, voiding any security the underlying encryption protocol is supposed to provide. For example, it allows decryption or injection of frames, and enables an attacker to replay frames.
Fix crash due to corrupted dib file.

The SuSEfirewall2 package before 3.6.312-2.13.1 in SUSE Linux Enterprise (SLE) Desktop 12 SP2, Server 12 SP2, and Server for Raspberry Pi 12 SP2; before 3.6.312.333-3.10.1 in SLE Desktop 12 SP3 and Server 12 SP3; before 3.6SVNr208-2.18.3.1 in SLE Server 11 SP4; before 3.6.312-5.9.1 in openSUSE Leap 42.2; and before 3.6.312.333-7.1 in openSUSE Leap 42.3 might allow remote attackers to bypass intended access restrictions on the portmap service by leveraging a missing source net restriction for rpc services.
