oxide-qt vulnerabilities
==========================
==========================
========================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in Oxide.
Software Description:
- oxide-qt: Web browser engine for Qt (QML plugin)
Details:
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 (application crash) or execute arbitrary code. (CVE-2016-1705)=
It was discovered that the PPAPI implementation does not validate the
origin of IPC messages to the plugin broker process. A remote attacker
could potentially exploit this to bypass sandbox protection mechanisms.
(CVE-2016-1706)
It was discovered that Blink does not prevent window creation by a
deferred frame. A remote attacker could potentially exploit this to bypas=
s
same origin restrictions. (CVE-2016-1710)
It was discovered that Blink does not disable frame navigation during a
detach operation on a DocumentLoader object. A remote attacker could
potentially exploit this to bypass same origin restrictions.
(CVE-2016-1711)
A use-after-free was discovered in Blink. If a user were tricked in to
opening a specially crafted website, an attacker could potentially exploi=
t
this to cause a denial of service via renderer process crash, or execute
arbitrary code. (CVE-2016-5127)
It was discovered that objects.cc in V8 does not prevent API interceptors=
from modifying a store target without setting a property. A remote
attacker could potentially exploit this to bypass same origin
restrictions. (CVE-2016-5128)
A memory corruption was discovered in V8. If a user were tricked in to
opening a specially crafted website, an attacker could potentially exploi=
t
this to cause a denial of service via renderer process crash, or execute
arbitrary code. (CVE-2016-5129)
A security issue was discovered in Chromium. A remote attacker could
potentially exploit this to spoof the currently displayed URL.
(CVE-2016-5130)
A use-after-free was discovered in libxml. If a user were tricked in to
opening a specially crafted website, an attacker could potentially exploi=
t
this to cause a denial of service via renderer process crash, or execute
arbitrary code. (CVE-2016-5131)
The Service Workers implementation in Chromium does not properly implemen=
t
the Secure Contexts specification during decisions about whether to
control a subframe. A remote attacker could potentially exploit this to
bypass same origin restrictions. (CVE-2016-5132)
It was discovered that Chromium mishandles origin information during prox=
y
authentication. A man-in-the-middle attacker could potentially exploit th=
is
to spoof a proxy authentication login prompt. (CVE-2016-5133)
It was discovered that the Proxy Auto-Config (PAC) feature in Chromium
does not ensure that URL information is restricted to a scheme, host and
port. A remote attacker could potentially exploit this to obtain sensitiv=
e
information. (CVE-2016-5134)
It was discovered that Blink does not consider referrer-policy informatio=
n
inside an HTML document during a preload request. A remote attacker could=
potentially exploit this to bypass Content Security Policy (CSP)
protections. (CVE-2016-5135)
It was discovered that the Content Security Policy (CSP) implementation i=
n
Blink does not apply http :80 policies to https :443 URLs. A remote
attacker could potentially exploit this to determine whether a specific
HSTS web site has been visited by reading a CSP report. (CVE-2016-5137)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.04 LTS:
liboxideqtcore0 1.16.5-0ubuntu0.16.04.1
Ubuntu 14.04 LTS:
liboxideqtcore0 1.16.5-0ubuntu0.14.04.1
In general, a standard system update will make all the necessary changes.=
