Details

An unspecified security issue was discovered in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2016-1673)

An issue was discovered with Document reattachment in Blink in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2016-1675)

A type confusion bug was discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-1677)

A use-after-free was discovered in the V8ValueConverter 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 (application crash) or execute arbitrary code. (CVE-2016-1679)

A use-after-free was discovered in Skia. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service (application crash) or execute arbitrary code. (CVE-2016-1680)

A security issue was discovered in ServiceWorker registration in Blink in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass Content Security Policy (CSP) protections. (CVE-2016-1682)

It was discovered that Blink permits cross-origin loading of stylesheets by a service worker even when the stylesheet download has an incorrect MIME type. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2016-1692)

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 (application crash) or execute arbitrary code. (CVE-2016-1695, CVE-2016-1703)

It was discovered that Blink does not prevent frame navigation during DocumentLoader detach operations. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2016-1697)

A parameter sanitization bug was discovered in the devtools subsystem in Blink. An attacker could potentially exploit this to bypass intended access restrictions. (CVE-2016-1699)

An out-of-bounds read was discovered in Skia. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service (application crash). (CVE-2016-1702)
