Details

A race condition was discovered in the MutationObserver implementation 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-2015-6789)

An issue was discovered with the page serializer in Blink. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit this to inject arbitrary script or HTML.
(CVE-2015-6790)

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...

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-2015-8548)

An integer overflow was discovered in the WebCursor::Deserialize function
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-2015-8664)
