Mozilla: Vulnerabilities found through code inspection (MFSA 2015-66)

The CairoTextureClientD3D9::BorrowDrawTarget function in the Direct3D 9 implementation in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 reads data from uninitialized memory locations, which has unspecified impact and attack vectors.

Mozilla: Use-after-free in workers while using XMLHttpRequest (MFSA 2015-65)

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 dedicated worker.

Mozilla: Use-after-free in Content Policy due to microtask execution error (MFSA 2015-63)

Use-after-free vulnerability in the CSPService::ShouldLoad function in the microtask implementation in Mozilla Firefox before 39.0, Firefox ESR 38.x before 38.1, and Thunderbird before 38.1 allows remote attackers to execute arbitrary code by leveraging client-side JavaScript that triggers removal of a DOM object on the basis of a Content Policy.

NSS: ECDSA signature validation fails to handle some signatures correctly (MFSA 2015-64)

Mozilla Network Security Services (NSS) before 3.19.1, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and other products, does not properly perform Elliptical Curve Cryptography (ECC) multiplications, which makes it easier for remote attackers to spoof ECDSA signatures via unspecified vectors.

Mozilla: Out-of-bound read while computing an oscillator rendering range in Web Audio (MFSA 2015-62)

The AudioParamTimeline::AudioNodeInputValue function in the Web Audio implementation in Mozilla Firefox before 39.0 and Firefox ESR 38.x before 38.1 does not properly calculate an oscillator rendering range, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via unspecified vectors.

Mozilla: Type confusion in Indexed Database Manager (MFSA 2015-61)

The IndexedDatabaseManager class in the IndexedDB implementation in Mozilla Firefox before 39.0 and Firefox ESR 31.x before 31.8 and 38.x before 38.1 misinterprets an unspecified IDBDatabase field as a pointer, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via unspecified vectors, related to a "type confusion" issue.

Mozilla: Local files or privileged URLs in pages can be opened into new tabs (MFSA 2015-60)

Mozilla Firefox 38.0 and Firefox ESR 38.0 allow user-assisted remote attackers to read arbitrary files or execute arbitrary JavaScript code with chrome privileges via a crafted web site that is accessed with unspecified mouse and keyboard actions. NOTE: this vulnerability exists because of a CVE-2015-0821 regression.

Mozilla: Miscellaneous memory safety hazards (rv:38.1) (MFSA 2015-59)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 39.0 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:31.8 / rv:38.1) (MFSA 2015-59)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 39.0, Firefox ESR 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.

Mozilla: Miscellaneous memory safety hazards (rv:31.8 / rv:38.1) (MFSA 2015-59)

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.

Mozilla: Use-after-free in workers while using XMLHttpRequest (MFSA 2015-65)

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.

NSS: incorrectly permited skipping of ServerKeyExchange (MFSA 2015-71)

Mozilla Network Security Services (NSS) before 3.19, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, Thunderbird before 38.1, and other products, does not properly determine state transitions for the TLS state machine, which allows man-in-the-middle attackers to defeat cryptographic protection mechanisms by blocking messages, as demonstrated by removing a forward-secrecy property by blocking a ServerKeyExchange message, aka a "SMACK SKIP-TLS" issue.

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.

Mozilla: Untrusted site hosting trusted page can intercept webchannel responses (MFSA 2015-56)

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.

Mozilla: Buffer overflow and out-of-bounds read while parsing MP4 video metadata (MFSA 2015-55)

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.

expat: Integer overflow leading to buffer overflow in XML_GetBuffer()

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.

Mozilla: Use-after-free due to Media Decoder Thread creation during shutdown (MFSA 2015-53)

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.

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.

Mozilla: Use-after-free during text processing with vertical text enabled (MFSA 2015-51)

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.

Mozilla: Out-of-bounds read and write in asm.js validation (MFSA 2015-50)

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.
