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 heap overflow 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 (application crash) or execute arbitrary code. (CVE-2016-1678) 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) An out-of-bounds memory access was discovered in libxslt.

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).
