CVE-2016-1646

Chromium-browser-stable 49.0.2623.108 fixes security issues:

Multiple security issues were found in upstream chromium 49.0.2623.87: an out-of-bounds read problem in V8 (CVE-2016-1646), use-after-free bugs in Navigation (CVE-2016-1647) and Extensions (CVE-2016-1648); a buffer overflow in libANGLE (CVE-2016-1649), various security issues found in internal audits, fuzzing, and other initiatives (CVE-2016-1650); multiple vulnerabilities in V8 were fixed in 4.9.385.33.

The ImageInputType::ensurePrimaryContent function in WebKit/Source/core/html/forms/ImageInputType.cpp in Blink, as used in Google Chrome before 49.0.2623.87, does not properly maintain the user agent shadow DOM, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that leverage "type confusion." (CVE-2016-1643)

WebKit/Source/core/layout/LayoutObject.cpp in Blink, as used in Google Chrome before 49.0.2623.87, does not properly restrict relayout scheduling, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted HTML document. (CVE-2016-1644)

Multiple integer signedness errors in the opj_j2k_update_image_data function in j2k.c in OpenJPEG, as used in PDFium in Google Chrome before 49.0.2623.87, allow remote attackers to cause a denial of service (incorrect cast and out-of-bounds write) or possibly have unspecified other impact via crafted JPEG 2000 data. (CVE-2016-1645)

The ContainerNode::parserRemoveChild function in WebKit/Source/core/dom/ContainerNode.cpp in Blink, as used in Google Chrome before 49.0.2623.75, mishandles widget updates, which makes it easier for remote attackers to bypass the Same Origin Policy via a crafted web site. (CVE-2016-1630)

The PPB_Flash_MessageLoop_Impl::InternalRun function in content/renderer/pepper/ppb_flash_message_loop_impl.cc in the Pepper plugin in Google Chrome before 49.0.2623.75 mishandles nested message loops, which allows remote attackers to bypass the Same Origin Policy via a crafted web site. (CVE-2016-1631)

The Extensions subsystem in Google Chrome before 49.0.2623.75 does not properly maintain own properties, which allows remote attackers to bypass intended access restrictions via crafted JavaScript code that triggers an incorrect cast, related to extensions/renderer/v8_helpers.h and gin/converter.h. (CVE-2016-1632)

Use-after-free vulnerability in Blink, as used in Google Chrome before 49.0.2623.75, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors. (CVE-2016-1633)

Use-after-free vulnerability in the StyleResolver::appendCSSStyleSheet function in WebKit/Source/core/css/resolver/StyleResolver.cpp in Blink, as used in Google Chrome before 49.0.2623.75, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted web site that triggers Cascading Style Sheets (CSS) style invalidation during a certain subtree-removal action. (2016-1634)

extensions/renderer/render_frame_observer_natives.cc in Google Chrome before 49.0.2623.75 does not properly consider object lifetimes and re-entrancy issues during OnDocumentElementCreated handling, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via unknown vectors. (CVE-2016-1635)

The PendingScript::notifyFinished function in WebKit/Source/core/dom/PendingScript.cpp in Google Chrome before 49.0.2623.75 relies on memory-cache information about integrity-check occurrences instead of integrity-check successes, which allows remote attackers to bypass the Subresource Integrity (aka SRI) protection mechanism by triggering two loads of the same resource. (CVE-2016-1636)

The SkATan2_255 function in effects/gradients/SkSweepGradient.cpp in Skia, as used in Google Chrome before 49.0.2623.75, mishandles arctangent calculations, which allows remote attackers to obtain sensitive…

A use-after-free was discovered when responding synchronously to permission requests. An attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1578)

An out-of-bounds read was discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash. (CVE-2016-1646)

A use-after-free was discovered in the navigation implementation in Chromium in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1647)

A buffer overflow was discovered in ANGLE. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1649)

An out-of-bounds write was discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code with the privileges of the sandboxed renderer process. (CVE-2016-1653)

An invalid read was discovered in the media subsystem in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash. (CVE-2016-1654)

It was discovered that frame removal during callback execution could trigger a use-after-free in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code with the privileges of the sandboxed renderer process. (CVE-2016-1655)

Multiple security issues were discovered in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1659)

Multiple security issues were discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process.
