Details

It was discovered that the ContainerNode::parserRemoveChild function in
Blink mishandled widget updates 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-2016-1630)

It was discovered that the PPB_Flash_MessageLoop_Impl::InternalRun
function in Chromium mishandled nested message loops. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit this to bypass same-origin restrictions.
(CVE-2016-1631)

Multiple use-after-frees were discovered in Blink. If a user were tricked
in to opening a specially crafted website, an attacker could potentially
exploit these to cause a denial of service via renderer crash or execute
arbitrary code with the privileges of the sandboxed render process.
(CVE-2016-1633, CVE-2016-1634, CVE-2016-1644)

It was discovered that the PendingScript::notifyFinished function in
Blink relied on memory-cache information about integrity-check occurrences
instead of integrity-check successes. If a user were tricked in to opening
a specially crafted website, an attacker could potentially exploit this to
bypass Subresource Integrity (SRI) protections. (CVE-2016-1636)

It was discovered that the SkATan2_255 function in Skia mishandled
arctangent calculations. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to obtain
sensitive information. (CVE-2016-1637)

A use-after-free was discovered 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, or execute
arbitrary code with the privileges of the user invoking the program.
(CVE-2016-1641)

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-2016-1642)

A type-confusion bug was discovered 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 render process.
(CVE-2016-1643)

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. (CVE-2016-2843)

An invalid cast was discovered 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 render process. (CVE-2016-2844)

It was discovered that the Content Security Policy (CSP) implementation in
Blink did not ignore a URL’s path component in the case of a ServiceWorker
fetch. If a user were tricked in to opening a specially crafted website,
an attacker could potentially exploit this to obtain sensitive
information. (CVE-2016-2845)
