Firefox

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.Show less

Use-after-free vulnerability in the CanonicalizeXPCOMParticipant function in Mozilla Firefox before 39.0 and Firefox ESR 31.x before 31.8 and 38.x before 38.1 allows remote attackers to execute arbitrary code via vectors involving attachment of an XMLHttpRequest object to a shared worker.Show less

The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.Show less

The update implementation in Mozilla Firefox before 38.0 on Windows does not ensure that the pathname for updater.exe corresponds to the application directory, which might allow local users to gain privileges via a Trojan horse file.Show less

The WebChannel.jsm module in Mozilla Firefox before 38.0 allows remote attackers to bypass the Same Origin Policy and obtain sensitive webchannel-response data via a crafted web site containing an IFRAME element referencing a different web site that is intended to read this data.Show less

Integer overflow in libstagefright in Mozilla Firefox before 38.0 allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow and out-of-bounds read) via an MP4 video file containing invalid metadata.Show less

Buffer overflow in the XML parser in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 allows remote attackers to execute arbitrary code by providing a large amount of compressed XML data, a related issue to CVE-2015-1283.Show less

Race condition in the nsThreadManager::RegisterCurrentThread function in Mozilla Firefox before 38.0 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and heap memory corruption) by leveraging improper Media Decoder Thread creation at the time of a shutdown.Show less

Mozilla Firefox before 38.0 on Android does not properly restrict writing URL data to the Android logging system, which allows attackers to obtain sensitive information via a crafted application that has a required permission for reading a log, as demonstrated by the READ_LOGS permission for the mixed-content violation log on Android 4.0 and earlier.Show less

Use-after-free vulnerability in the SetBreaks function in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a document containing crafted text in conjunction with a Cascading Style Sheets (CSS) token sequence containing properties related to vertical text.Show less

The asm.js implementation in Mozilla Firefox before 38.0 does not properly determine heap lengths during identification of cases in which bounds checking may be safely skipped, which allows remote attackers to trigger out-of-bounds write operations and possibly execute arbitrary code, or trigger out-of-bounds read operations and possibly obtain sensitive information from process memory, via crafted JavaScript.Show less

Mozilla Firefox before 38.0 does not recognize a referrer policy delivered by a referrer META element in cases of context-menu navigation and middle-click navigation, which allows remote attackers to obtain sensitive information by reading web-server Referer logs that contain private data in a URL, as demonstrated by a private path component.Show less

Heap-based buffer overflow in the SVGTextFrame class in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 allows remote attackers to execute arbitrary code via crafted SVG graphics data in conjunction with a crafted Cascading Style Sheets (CSS) token sequence.Show less

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 38.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.Show less

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.Show less

GStreamer before 1.4.5, as used in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 on Linux, allows remote attackers to cause a denial of service (buffer over-read and application crash) or possibly execute arbitrary code via crafted H.264 video data in an m4v file.Show less

Race condition in the AsyncPaintWaitEvent::AsyncPaintWaitEvent function in Mozilla Firefox before 37.0.2 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via a crafted plugin that does not properly complete initialization.Show less

The HTTP Alternative Services feature in Mozilla Firefox before 37.0.1 allows man-in-the-middle attackers to bypass an intended X.509 certificate-verification step for an SSL server by specifying that server in the uri-host field of an Alt-Svc HTTP/2 response header.Show less

The Reader mode feature in Mozilla Firefox before 37.0.1 on Android, and Desktop Firefox pre-release, does not properly handle privileged URLs, which makes it easier for remote attackers to execute arbitrary JavaScript code with chrome privileges by leveraging the ability to bypass the Same Origin Policy.Show less

Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 do not properly restrict resource: URLs, which makes it easier for remote attackers to execute arbitrary JavaScript code with chrome privileges by leveraging the ability to bypass the Same Origin Policy, as demonstrated by the resource: URL associated with PDF.js.Show less
