Details:

It was discovered that the DOM tree could be corrupted during parsing 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 or cause a denial of service. (CVE-2015-1291)

An issue was discovered in NavigatorServiceWorker::serviceWorker 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-2015-1292)

An issue was discovered in the DOM implementation 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-2015-1293)

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 via renderer crash, or execute arbitrary
code with the privileges of the sandboxed render process. (CVE-2015-1294)

A use-after-free was discovered in the shared-timer 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-2015-1299)

It was discovered that the availability of iframe Resource Timing API
times was not properly restricted in some circumstances. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit this to obtain sensitive information. (CVE-2015-1300)

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-2015-1301)

A heap corruption issue was discovered in oxide::JavaScriptDialogManager.
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-2015-1332)
