The nsTSubstring::ReplacePrep function in Mozilla Firefox before 40.0, Firefox ESR 38.x before 38.2, and Firefox OS before 2.2 might allow remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors, related to an "overflow."

The decrease_ref_count function in libvpx in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via malformed WebM video data.

Heap-based buffer overflow in the resize_context_buffers function in libvpx in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to execute arbitrary code via malformed WebM video data.

The js::jit::AssemblerX86Shared::lock_addl function in the JavaScript implementation in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to cause a denial of service (application crash) by leveraging the use of shared memory and accessing (1) an Atomics object or (2) a SharedArrayBuffer object.

Mozilla Firefox before 40.0 allows man-in-the-middle attackers to bypass a mixed-content protection mechanism via a feed: URL in a POST request.

mar_read.c in the Updater in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows local users to gain privileges or cause a denial of service (out-of-bounds write) via a crafted name of a Mozilla Archive (aka MAR) file.

Race condition in the Mozilla Maintenance Service in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 on Windows allows local users to write to arbitrary files and consequently gain privileges via vectors involving a hard link to a log file during an update.

The xmlreader in libxml allows remote attackers to cause a denial of service (memory consumption) via crafted XML data, related to an XML Entity Expansion (XEE) attack.

The PDF reader in Mozilla Firefox before 39.0.3, Firefox ESR 38.x before 38.1.1, and Firefox OS before 2.2 allows remote attackers to bypass the Same Origin Policy, and read arbitrary files or gain privileges, via vectors involving crafted JavaScript code and a native setter, as exploited in the wild in August 2015.

The ucnv_io_getConverterName function in common/ucnv_io.cpp in International Components for Unicode (ICU), as used in Google Chrome before 44.0.2403.89, mishandles converter names with initial x- substrings, which allows remote attackers to cause a denial of service (read of uninitialized memory) or possibly have unspecified other impact via a crafted file.

The dissect_wccp2r1_address_table_info function in epan/dissectors/packet-wccp.c in the WCCP dissector in Wireshark 1.12.x before 1.12.6 does not properly determine whether enough memory is available for storing IP address strings, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The read_request_line function in server/protocol.c in the Apache HTTP Server 2.4.12 does not initialize the protocol structure member, which allows remote attackers to cause a denial of service (NULL pointer dereference and process crash) by sending a request that lacks a method to an installation that enables the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI.

Django before 1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 uses an incorrect regular expression, which allows remote attackers to inject arbitrary headers and conduct HTTP response splitting attacks via a newline character in an (1) email message to the EmailValidator, a (2) URL to the URLValidator, or unspecified vectors to the (3) validate_ipv4_address or (4) validate_slug validator.

The session backends in Django before 1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 allows remote attackers to cause a denial of service (session store consumption) via multiple requests with unique session keys.
