Mozilla: Cross-origin information leak through web workers error events (MFSA 2015-140)

The importScripts function in the Web Workers API implementation in Mozilla Firefox before 43.0 allows remote attackers to bypass the Same Origin Policy by triggering use of the no-cors mode in the fetch API to attempt resource access that throws an exception, leading to information disclosure after a rethrow.

Mozilla: Cross-site reading attack through data: and view-source: URIs (MFSA 2015-149)

Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allow remote attackers to bypass the Same Origin Policy via data: and view-source: URIs.

The OPVPWrapper::loadDriver function in oprs/OPVPWrapper.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allows local users to gain privileges via a Trojan horse driver in the same directory as the PDF file.

Mozilla: Integer overflow in MP4 playback in 64-bit versions (MFSA 2015-146)

Integer overflow in the MPEG4Extractor::readMetaData function in MPEG4Extractor.cpp in libstagefright in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 on 64-bit platforms allows remote attackers to execute arbitrary code via a crafted MP4 video file that triggers a buffer overflow.

Mozilla: Integer overflow allocating extremely large textures (MFSA 2015-139)

Integer overflow in the mozilla::layers::BufferTextureClient::AllocateForSurface function in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code by triggering a graphics operation that requires a large texture allocation.

Heap-based buffer overflow in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allows remote attackers to execute arbitrary code via a crafted PDF file.

Mozilla: Hash in data: URI is incorrectly parsed (MFSA 2015-141)

Mozilla Firefox before 43.0 mishandles the # (number sign) character in a data: URI, which allows remote attackers to spoof web sites via unspecified vectors.

Mozilla: Use-after-free in WebRTC when datachannel is used after being destroyed (MFSA 2015-138)

Use-after-free vulnerability in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code by triggering attempted use of a data channel that has been closed by a WebRTC function.

cups-filters: possible heap-based buffer overflows due to the use of gmalloc

Multiple integer overflows in (1) OPVPOutputDev.cxx and (2) oprs/OPVPSplash.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allow remote attackers to execute arbitrary code via a crafted PDF file, which triggers a heap-based buffer overflow.

Mozilla: Firefox allows for control characters to be set in cookies (MFSA 2015-137)

Mozilla Firefox before 43.0 stores cookies containing vertical tab characters, which allows remote attackers to obtain sensitive information by reading HTTP Cookie headers.

libvirt: unsafe usage of paths under /proc/$PID/root

The LXC driver (lxc/lxc_driver.c) in libvirt 1.0.1 through 1.2.1 allows local users to (1) delete arbitrary host devices via the virDomainDeviceDettach API and a symlink attack on /dev in the container; (2) create arbitrary nodes (mknod) via the virDomainDeviceAttach API and a symlink attack on /dev in the container; and cause a denial of service (shutdown or reboot host OS) via the (3) virDomainShutdown or (4) virDomainReboot API and a symlink attack on /dev/initctl in the container, related to "paths under /proc/$PID/root" and the virInitctlSetRunLevel function.

Mozilla: Same-origin policy violation using perfomance.getEntries and history navigation (MFSA 2015-136)

Mozilla Firefox before 43.0 does not properly restrict the availability of IFRAME Resource Timing API times, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via crafted JavaScript code that leverages history.back and performance.getEntries calls, a related issue to CVE-2015-1300.

Mozilla: Underflow through code inspection (MFSA 2015-145)

Integer underflow in the RTPReceiverVideo::ParseRtpPacket function in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 might allow remote attackers to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a crafted WebRTC RTP packet.

json-c: hash collision DoS

The hash functionality in json-c before 0.12 allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted JSON data, involving collisions.

Mozilla: Crash with JavaScript variable assignment with unboxed objects (MFSA 2015-135)

Mozilla Firefox before 43.0 does not properly store the properties of unboxed objects, which allows remote attackers to execute arbitrary code via crafted JavaScript variable assignments.

Off-by-one error in the DecompressRTF function in ytnef.c in Yerase's TNEF Stream Reader allows remote attackers to cause a denial of service (crash) via a crafted TNEF file, which triggers a buffer overflow.

Mozilla: Buffer overflows found through code inspection (MFSA 2015-144)

Buffer overflow in the DirectWriteFontInfo::LoadFontFamilyData function in gfx/thebes/gfxDWriteFontList.cpp in Mozilla Firefox before 43.0 might allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted font-family name.

json-c: buffer overflow if size_t is larger than int

Buffer overflow in the printbuf APIs in json-c before 0.12 allows remote attackers to cause a denial of service via unspecified vectors.

Mozilla: Miscellaneous memory safety hazards (rv:43.0) (MFSA 2015-134)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 43.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla: Miscellaneous memory safety hazards (rv:38.5) (MFSA 2015-134)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
