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:

A use-after-free 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-2015-1243)

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-2015-1250)

Update instructions:

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

Ubuntu 15.04:
  liboxideqtcore0                 1.6.6-0ubuntu0.15.04.1

Ubuntu 14.10:
  liboxideqtcore0                 1.6.6-0ubuntu0.14.10.1

Ubuntu 14.04 LTS:
  liboxideqtcore0                 1.6.6-0ubuntu0.14.04.1

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