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

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

- Ubuntu 15.04
- 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:

It was discovered that Chromium did not properly consider the scheme when
determining whether a URL is associated with a WebUI SiteInstance. If a
user were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to bypass security restrictions.
(CVE-2015-1266)

It was discovered that Blink did not properly restrict the creation
context during creation of a DOM wrapper. If a user were tricked in to
opening a specially crafted website, an attacker could potentially exploit
this to bypass same-origin restrictions. (CVE-2015-1267, CVE-2015-1268)

It was discovered that Chromium did not properly canonicalize DNS hostnames
before comparing to HSTS or HPKP preload entries. An attacker could
potentially exploit this to bypass intended access restrictions.
(CVE-2015-1269)

Update instructions:

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

Ubuntu 15.04:
  liboxideqtcore0                 1.7.9-0ubuntu0.15.04.1

Ubuntu 14.10:
  liboxideqtcore0                 1.7.9-0ubuntu0.14.10.1

Ubuntu 14.04 LTS:
  liboxideqtcore0                 1.7.9-0ubuntu0.14.04.1

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