oxide-qt vulnerabilities
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Oxide.

Software Description:
- oxide-qt: Web browser engine library for Qt

Details:

A type confusion bug 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 render process. (CVE-2014-1730)

A type confusion bug was discovered 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-2014-1731)

Multiple security issues including memory safety bugs were discovered in
Chromium. If a user were tricked in to opening a specially crafted website,
an attacker could potentially exploit these to cause a denial of service via
application crash or execute arbitrary code with the privileges of the
user invoking the program. (CVE-2014-1735, CVE-2014-3162)

Multiple use-after-free issues were discovered in the WebSockets
implementation. If a user were tricked in to opening a specially crafted
website, an attacker could potentially exploit these to cause a denial of
service via application crash or execute arbitrary code with the
privileges of the user invoking the program. (CVE-2014-1740)

Multiple integer overflows were discovered in CharacterData
implementation. If a user were tricked in to opening a specially crafted
website, an attacker could potentially exploit these to cause a denial of
service via renderer crash or execute arbitrary code with the privileges
of the sandboxed render process. (CVE-2014-1741)

Multiple use-after-free issues were discovered in Blink. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service via renderer crash
or execute arbitrary code with the privileges of the sandboxed render
process. (CVE-2014-1742, CVE-2014-1743)

An integer overflow bug was discovered 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-2014-1744)

An out-of-bounds read was discovered in Chromium. If a user were tricked
in to opening a specially crafter website, an attacker could potentially
exploit this to cause a denial of service via application crash.
(CVE-2014-1746)

It was discovered that Blink allowed scrollbar painting to extend in to
the parent frame in some circumstances. An attacker could potentially
exploit this to conduct clickjacking attacks via UI redress.
(CVE-2014-1748)

An integer underflow was discovered in Blink. If a user were tricked in to
opening a specially crafter 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-2014-3152)

A use-after-free was discovered in Chromium. If a use 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-2014-3154)

A security issue was discovered in the SPDY implementation. 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-2014-3155)

A heap overflow was discovered in Chromium. If a use 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-2014-3157)

It was discovered that Blink did not enforce security rules for
subresource loading in SVG images. If a user opened a site that embedded a
specially crafted image, an attacker could exploit this to log page views.
(CVE-2014-3160)

It was discovered that the SpeechInput feature in Blink could be activated
without consent or any visible indication. If a user were tricked in to
opening a specially crafted website, an attacker could exploit this to
eavesdrop on the user. (CVE-2014-3803)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
  liboxideqtcore0                 1.0.4-0ubuntu0.14.04.1
  oxideqt-codecs                  1.0.4-0ubuntu0.14.04.1
  oxideqt-codecs-extra            1.0.4-0ubuntu0.14.04.1

In general, a standard system update will make all the necessary changes.
