Ubuntu Security Notice (C) 2016 Canonical, Inc. / NASL script (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

A race condition was discovered in the MutationObserver 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-2015-6789)

An issue was discovered with the page serializer in Blink. If a user
were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to inject arbitrary script or HTML.
(CVE-2015-6790)

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-2015-6791)

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-2015-8548)

An integer overflow was discovered in the WebCursor::Deserialize
function in Chromium. 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-2015-8664).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected liboxideqtcore0 package.
