Ubuntu Security Notice USN-2556-1
April 07, 2015

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:

It was discovered that Chromium did not properly handle the interaction
of IPC, the gamepad API and V8. If a user were tricked in to opening a
specially crafted website, an attacker could potentially exploit this to
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2015-1233)

A buffer overflow was discovered in the GPU service. 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. (CVE-2015-1234)

It was discovered that Oxide did not correctly manage the lifetime of
BrowserContext, resulting in a potential use-after-free in some
circumstances. 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-2015-1317)

Update instructions:

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

Ubuntu 14.10:
liboxideqtcore0 1.5.6-0ubuntu0.14.10.1

Ubuntu 14.04 LTS:
liboxideqtcore0 1.5.6-0ubuntu0.14.04.2

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