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

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

– Ubuntu 14.10
– Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Oxide.

Software Description:
– oxide-qt: Web browser engine library for Qt (QML plugin)

Details:

A use-after-free bug 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 cause a denial of service via renderer
crash or execute arbitrary code with the privileges of the sandboxed
render process. (CVE-2015-1209)

It was discovered that V8 did not properly consider frame access
restrictions when throwing exceptions 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.
(CVE-2015-1210)

It was discovered that Chromium did not properly restrict the URI scheme
during ServiceWorker registration. If a user were tricked in to
downloading and opening a specially crafted HTML file, an attacker could
potentially exploit this to bypass security restrictions. (CVE-2015-1211)

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-2015-1212)

Update instructions:

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

Ubuntu 14.10:
liboxideqtcore0 1.4.3-0ubuntu0.14.10.1
oxideqt-codecs 1.4.3-0ubuntu0.14.10.1
oxideqt-codecs-extra 1.4.3-0ubuntu0.14.10.1

Ubuntu 14.04 LTS:
