Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that ContainerNode::parserInsertBefore in Blink
would incorrectly proceed with a DOM tree insertion in some
circumstances. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to bypass
same origin restrictions. (CVE-2015-6755)

A use-after-free was discovered in the service worker implementation
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-2015-6757)

It was discovered that Blink did not ensure that the origin of
LocalStorage resources are considered unique. If a user were tricked
in to opening a specially crafted website, an attacker could
potentially exploit this to obtain sensitive information.
(CVE-2015-6759)

A race condition and memory corruption was discovered in FFmpeg. 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-2015-6761)

It was discovered that CSSFontFaceSrcValue::fetch in Blink did not use
CORS in some circumstances. If a user were tricked in to opening a
specially crafted website, an attacker could potentially exploit this
to bypass same origin restrictions. (CVE-2015-6762)

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-2015-6763)

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-2015-7834).

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.
