Ubuntu Security Notice USN-2877-1
January 27, 2016

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

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

- Ubuntu 15.10
- Ubuntu 15.04
- 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 bad cast was discovered in V8. 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-2016-1612)

An issue was discovered when initializing the UnacceleratedImageBufferSurface
class in Blink. If a user were tricked in to opening a specially crafted
website, an attacker could potentially exploit this to obtain sensitive
information. (CVE-2016-1614)

An issue was discovered with the CSP implementation in Blink. If a user
were tricked in to opening a specially crafted website, an attacker could
potentially exploit this to determine whether specific HSTS sites had been
visited by reading a CSP report. (CVE-2016-1617)

An issue was discovered with random number generator in Blink. An attacker
could potentially exploit this to defeat cryptographic protection
mechanisms. (CVE-2016-1618)

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-2016-1620)

Multiple security issues were discovered in V8. 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
renderer crash or execute arbitrary code with the privileges of the
sandboxed render process. (CVE-2016-2051)

Multiple security issues were discovered in Harfbuzz. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service via renderer
crash or execute arbitrary code with the privileges of the sandboxed
render process. (CVE-2016-2052)

Update instructions:

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

Ubuntu 15.10:
liboxideqtcore0 1.12.5-0ubuntu0.15.10.1

Ubuntu 15.04:
liboxideqtcore0 1.12.5-0ubuntu0.15.04.1

Ubuntu 14.04 LTS:
liboxideqtcore0 1.12.5-0ubuntu0.14.04.1

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