Summary
======
The package webkit2gtk before version 2.16.1-1 is vulnerable to
multiple issues including arbitrary code execution, access restriction
bypass, content spoofing, cross-site scripting, information disclosure,
same-origin policy bypass and denial of service.

Resolution
=========
Upgrade to 2.16.1-1.

# pacman -Syu "webkit2gtk>=2.16.1-1"

The problems have been fixed upstream in version 2.16.1.

Workaround
=========
None.

Description
==========
- CVE-2016-9642 (denial of service)

JavaScriptCore in WebKitGTK+ before 2.16.0 allows attackers to cause a
denial of service (out-of-bounds heap read) via a crafted Javascript
file.

- CVE-2016-9643 (denial of service)

The regex code in WebKitGTK+ before 2.14.6 allows remote attackers to
cause a denial of service (memory consumption) as demonstrated in a
large number of ($ (open parenthesis and dollar) followed by {-2,16}
and a large number of +) (plus close parenthesis).

- CVE-2017-2367 (same-origin policy bypass)

An issue has been found in WebKit, allowing remote attackers to bypass
the Same Origin Policy and obtain sensitive information via a crafted
web site.

An issue has been found in WebKit, allowing remote attackers to spoof
the address bar by leveraging text input during the loading of a page.

- CVE-2017-2377 (denial of service)

This issue involves the “WebKit Web Inspector” component. It allows
attackers to cause a denial of service (memory corruption and
application crash) by leveraging a window-close action during a
debugger-pause state.

- CVE-2017-2386 (same-origin policy bypass)

An issue has been found in WebKit, allowing remote attackers to bypass
the Same Origin Policy and obtain sensitive information via a crafted
web site.

An issue has been found in WebKit, allowing attackers to execute
arbitrary code or cause a denial of service (memory corruption) via a
crafted app.

arbitrary code or cause a denial of service (memory corruption and
application crash) via a crafted web site.

- CVE-2017-2405 (arbitrary code execution)

An issue has been found in the “WebKit Web Inspector” component. It
allows remote attackers to execute arbitrary code or cause a denial of
service (memory corruption and application crash) via a crafted web
site.

- CVE-2017-2415 (arbitrary code execution)

An issue has been found in WebKit, allowing remote attackers to execute
arbitrary code by leveraging an unspecified “type confusion.”.
