lib/moodlelib.php in Moodle through 2.5.9, 2.6.x before 2.6.9, 2.7.x before 2.7.6, and 2.8.x before 2.8.4, when the theme uses the blocks-regions feature, establishes the course state at an incorrect point in the login-validation process, which allows remote attackers to obtain sensitive course information via unspecified vectors.

Moodle 2.8.x before 2.8.6 does not consider the tool/monitor:subscribe capability before entering subscriptions to site-wide event-monitor rules, which allows remote authenticated users to obtain sensitive information via a subscription request.

httpd: HTTP request smuggling attack against chunked request parser

The chunked transfer coding implementation in the Apache HTTP Server before 2.4.14 does not properly parse chunk headers, which allows remote attackers to conduct HTTP request smuggling attacks via a crafted request, related to mishandling of large chunk-size values and invalid chunk-extension characters in modules/http/http_filters.c.

qemu: insecure temporary file use in /net/slirp.c

The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program.

PortletBridge: information disclosure via auto-dispatching of non-JSF resources

The PortletRequestDispatcher in PortletBridge, as used in Red Hat JBoss Portal 6.2.0, does not properly enforce the security constraints of servlets, which allows remote attackers to gain access to resources via a request that asks to render a non-JSF resource.

glibc: calloc may return non-zero memory

The calloc function in the glibc package in Red Hat Enterprise Linux (RHEL) 6.7 and 7.2 does not properly initialize memory areas, which might allow context-dependent attackers to cause a denial of service (hang or crash) via unspecified vectors.

The CFNetwork FTPProtocol component in Apple iOS before 9 allows remote FTP proxy servers to trigger TCP connection attempts to intranet hosts via crafted responses.

The EFI component in Apple OS X before 10.11 allows physically proximate attackers to modify firmware during the EFI update process by inserting an Apple Ethernet Thunderbolt adapter with crafted code in an Option ROM, aka a "Thunderstrike" issue. NOTE: this issue exists because of an incomplete fix for CVE-2014-4498.

Apple OS X before 10.11 does not ensure that the keychain's lock state is displayed correctly, which has unspecified impact and attack vectors.

The decode_ihdr_chunk function in libavcodec/pngdec.c in FFmpeg before 2.7.2 does not enforce uniqueness of the IHDR (aka image header) chunk in a PNG image, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted image with two or more of these chunks.

The destroy_buffers function in libavcodec/sanm.c in FFmpeg before 2.7.2 does not properly maintain height and width values in the video context, which allows remote attackers to cause a denial of service (segmentation violation and application crash) or possibly have unspecified other impact via crafted LucasArts Smush video data.

The allocate_buffers function in libavcodec/alac.c in FFmpeg before 2.7.2 does not initialize certain context data, which allows remote attackers to cause a denial of service (segmentation violation) or possibly have unspecified other impact via crafted Apple Lossless Audio Codec (ALAC) data.

CFNetwork in Apple iOS before 9.1 and OS X before 10.11.1 does not properly consider the uppercase-versus-lowercase distinction during cookie parsing, which allows remote web servers to overwrite cookies via unspecified vectors.

The Swift implementation in Apple Xcode before 7.1 mishandles type conversion, which has unspecified impact and attack vectors.

Apple Mac EFI before 2015-002, as used in OS X before 10.11.1 and other products, mishandles arguments, which allows attackers to reach "unused" functions via unspecified vectors.

Keychain Access in Apple OS X before 10.11.2 and tvOS before 9.1 improperly interacts with Keychain Agent, which allows attackers to spoof the Keychain Server via unspecified vectors.

Corega CG-WLBARAGM devices provide an open proxy service, which allows remote attackers to trigger outbound network traffic via unspecified vectors.

kernel: usbvision: crash on invalid USB device descriptors

The usbvision driver in the Linux kernel package 3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red Hat Enterprise Linux (RHEL) 7.1 allows physically proximate attackers to cause a denial of service (panic) via a nonzero bInterfaceNumber value in a USB device descriptor.

libksba: encoding of invalid utf-8 strings in DN decoder src/dn.c (append_quoted, append_atv)

The append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.3 allows remote attackers to cause a denial of service (out-of-bounds read) by clearing the high bit of the byte after invalid utf-8 encoded data.

php: improper nul termination leading to out-of-bounds read in get_icu_value_internal

The get_icu_value_internal function in ext/intl/locale/locale_methods.c in PHP before 5.5.36, 5.6.x before 5.6.22, and 7.x before 7.0.7 does not ensure the presence of a '\0' character, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted locale_get_primary_language call.
