Heap-based buffer overflow in the opj_j2k_read_SPCod_SPCoc function in j2k.c in OpenJPEG, as used in PDFium in Google Chrome before 51.0.2704.63, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document.

git: path_name() integer truncation and overflow leading to buffer overflow

revision.c in git before 2.7.4 uses an incorrect integer data type, which allows remote attackers to execute arbitrary code via a (1) long filename or (2) many nested trees, leading to a heap-based buffer overflow.

libavcodec/tiff.c in FFmpeg before 2.8.6 does not properly validate RowsPerStrip values and YCbCr chrominance subsampling factors, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted TIFF file, related to the tiff_decode_tag and decode_frame functions.

chromium-browser: out-of-bounds read in pdfium

core/fxge/ge/fx_ge_text.cpp in PDFium, as used in Google Chrome before 51.0.2704.63, miscalculates certain index values, which allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted PDF document.

chromium-browser: out-of-bounds read in pdfium

The CPDF_DIBSource::CreateDecoder function in core/fpdfapi/fpdf_render/fpdf_render_loadimage.cpp in PDFium, as used in Google Chrome before 51.0.2704.63, mishandles decoder-initialization failure, which allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted PDF document.

chromium-browser: information leak in extensions

The renderer implementation in Google Chrome before 51.0.2704.63 does not properly restrict public exposure of classes, which allows remote attackers to obtain sensitive information via vectors related to extensions.

chromium-browser: out-of-bounds read in v8

The regexp (aka regular expression) implementation in Google V8 before 5.0.71.40, as used in Google Chrome before 51.0.2704.63, mishandles external string sizes, which allows remote attackers to cause a denial of service (out-of-bounds read) via crafted JavaScript code.

graphite2: multiple font parsing vulnerabilities (Mozilla MFSA 2016-37)

The graphite2::Slot::getAttr function in Slot.cpp in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted Graphite smart font, a different vulnerability than CVE-2016-2800.

chromium-browser: heap use-after-free in autofill

The Autofill implementation in Google Chrome before 51.0.2704.63 mishandles the interaction between field updates and JavaScript code that triggers a frame deletion, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted web site, a different vulnerability than CVE-2016-1701.

rubygem-activesupport: Possible Denial of Service attack in Active Support in merge_element()

The (1) jdom.rb and (2) rexml.rb components in Active Support in Ruby on Rails before 4.1.11 and 4.2.x before 4.2.2, when JDOM or REXML is enabled, allow remote attackers to cause a denial of service (SystemStackError) via a large XML document depth.

chromium-browser: limited cross-origin bypass in serviceworker

WebKit/Source/core/css/StyleSheetContents.cpp in Blink, as used in Google Chrome before 51.0.2704.63, permits cross-origin loading of CSS stylesheets by a ServiceWorker even when the stylesheet download has an incorrect MIME type, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.

rubygem-rack: Potential Denial of Service Vulnerability in Rack normalize_params()

lib/rack/utils.rb in Rack before 1.5.4 and 1.6.x before 1.6.2, as used with Ruby on Rails 3.x and 4.x and other products, allows remote attackers to cause a denial of service (SystemStackError) via a request with a large parameter depth.

chromium-browser: hpkp pins removed on cache clearance

browser/browsing_data/browsing_data_remover.cc in Google Chrome before 51.0.2704.63 deletes HPKP pins during cache clearing, which makes it easier for remote attackers to spoof web sites via a valid certificate from an arbitrary recognized Certification Authority.

openssl: Padding oracle in AES-NI CBC MAC check

The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169.

chromium-browser: cross-origin bypass in extension bindings

The extensions subsystem in Google Chrome before 51.0.2704.79 does not properly restrict bindings access, which allows remote attackers to bypass the Same Origin Policy via unspecified vectors.

chromium-browser: cross-origin bypass in blink

The FrameLoader::startLoad function in WebKit/Source/core/loader/FrameLoader.cpp in Blink, as used in Google Chrome before 51.0.2704.79, does not prevent frame navigations during DocumentLoader detach operations, which allows remote attackers to bypass the Same Origin Policy via crafted JavaScript code.

chromium-browser: information leak in extension bindings

The createCustomType function in extensions/renderer/resources/binding.js in the extension bindings in Google Chrome before 51.0.2704.79 does not validate module types, which might allow attackers to load arbitrary modules or obtain sensitive information by leveraging a poisoned definition.

OpenSSL: X509_ATTRIBUTE memory leak

The ASN1_TFLG_COMBINE implementation in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zh, 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1q, and 1.0.2 before 1.0.2e mishandles errors caused by malformed X509_ATTRIBUTE data, which allows remote attackers to obtain sensitive information from process memory by triggering a decoding failure in a PKCS#7 or CMS application.

openssl: EVP_EncodeUpdate overflow

Integer overflow in the EVP_EncodeUpdate function in crypto/evp/encode.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a large amount of binary data.
