Summary

The package qt5-webengine before version 5.7.1-1 is vulnerable to
multiple issues including arbitrary code execution, content spoofing,
cross-site scripting, information disclosure and same-origin policy
bypass.

Resolution

Upgrade to 5.7.1-1.

pacman -Syu “qt5-webengine>=5.7.1-1”

The problems have been fixed upstream in version 5.7.1.

Workaround

None.

Description

• CVE-2016-5133 (content spoofing)

Google Chrome before 52.0.2743.82 mishandles origin information during
proxy authentication, which allows man-in-the-middle attackers to spoof
a proxy-authentication login prompt or trigger incorrect credential
storage by modifying the client-server data stream.

• CVE-2016-5147 (cross-site scripting)

Blink, as used in Google Chrome, mishandles deferred page loads, which
allows remote attackers to inject arbitrary web script or HTML via a
crafted web site, aka “Universal XSS (UXSS).”

• CVE-2016-5153 (arbitrary code execution)

The Web Animations implementation in Blink improperly relies on list
iteration, which allows remote attackers to cause a denial of service
(use-after-destruction) or possibly have unspecified other impact via a
crafted web site.

• CVE-2016-5155 (content spoofing)

Chromium does not properly validate access to the initial document,
which allows remote attackers to spoof the address bar via a crafted
web site.

• CVE-2016-5161 (information disclosure)

The EditingStyle::mergeStyle function in
WebKit/Source/core/editing/EditingStyle.cpp in Blink mishandles custom
properties, which allows remote attackers to cause a denial of service
or possibly have unspecified other impact via a crafted web site that
leverages “type confusion” in the StylePropertySerializer class.

• CVE-2016-5166 (information disclosure)

The download implementation in Chromium does not properly restrict
saving a file:// URL that is referenced by an http:// URL, which makes
it easier for user-assisted remote attackers to discover NetNTLM hashes
and conduct SMB relay attacks via a crafted web page that is accessed
with the “Save page as” menu choice.

• CVE-2016-5170 (arbitrary code execution)

WebKit/Source/bindings/modules/v8/V8BindingForModules.cpp in Blink does
not properly consider getter side effects during array key conversion,
which allows remote attackers to cause a denial of service (use-after-
free) or possibly have unspecified other impact via crafted Indexed
Database (aka IndexedDB) API calls.

• CVE-2016-5171 (arbitrary code execution)

WebKit/Source/bindings/templates/interface.cpp in Blink does not
prevent certain constructor calls, which allows remote attackers to
cause a denial of service (use-after-free) or possibly have unspecified
other impact via crafted JavaScript code.

• CVE-2016-5172 (information disclosure)

The parser in Google V8 mishandles scopes, which allows remote
attackers to obtain sensitive information from arbitrary memory
locations via crafted JavaScript code.

• CVE-2016-5181 (cross-site scripting)

An universal XSS flaw was found in the Blink component of the Chromium
browser.

• CVE-2016-5185 (arbitrary code execution)

An use after free flaw was found in the Blink component of the Chromium
browser.

• CVE-2016-5186 (information disclosure)

An out of bounds read flaw was found in the DevTools component of the
Chromium browser.

• CVE-2016-5187 (content spoofing)

An URL spoofing flaw was found in the Chromium browser.

• CVE-2016-5188 (content spoofing)

An UI spoofing flaw was found in the Chromium browser.

• CVE-2016-5192 (same-origin policy bypass)

A cross-origin bypass flaw was found in the Blink component of the
Chromium browser.

• CVE-2016-5198 (arbitrary code execution)

An out of bounds memory access flaw was found in the V8 component of
the Chromium browser.

Impact

A remote attacker can access sensitive information, spoof content,
bypass security measures or execute arbitrary code on the affected
host.
