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

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

- Ubuntu 15.10
- 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:

The DOM implementation in Chromium did not properly restrict frame-attach
operations from occurring during or after frame-detach operations. If a
user were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to bypass same-origin restrictions.
(CVE-2016-1623)

An integer underflow was discovered in Brotli. 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-2016-1624)

Update instructions:

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

Ubuntu 15.10:
  liboxideqtcore0                 1.12.6-0ubuntu0.15.10.1

Ubuntu 14.04 LTS:
  liboxideqtcore0                 1.12.6-0ubuntu0.14.04.1

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