Details

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. (CVE-2016-3679)
