Ubuntu Security Notice (C) 2014 Canonical, Inc. / NASL script (C) 2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Christian Holler, Terrence Cole, Jesse Ruderman, Gary Kwong, Eric
Rescorla, Jonathan Kew, Dan Gohman, Ryan VanderMeulen, Carsten Book,
Andrew Sutherland, Byron Campen, Nicholas Nethercote, Paul Adenot,
David Baron, Julian Seward and Sotaro Ikeda discovered multiple memory
safety issues in Firefox. 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 application crash, or execute
arbitrary code with the privileges of the user invoking Firefox.
(CVE-2014-1477, CVE-2014-1478)

Cody Crews discovered a method to bypass System Only Wrappers. An
attacker could potentially exploit this to steal confidential data or
execute code with the privileges of the user invoking Firefox.
(CVE-2014-1479)

Jordi Chancel discovered that the downloads dialog did not implement a
security timeout before button presses are processed. An attacker
could potentially exploit this to conduct clickjacking attacks.
(CVE-2014-1480)

Fredrik Lönnqvist discovered a use-after-free in Firefox. An attacker
could potentially exploit this to cause a denial of service via
application crash, or execute arbitrary code with the priviliges of
the user invoking Firefox. (CVE-2014-1482)

Jordan Milne discovered a timing flaw when using
document.elementFromPoint and document.caretPositionFromPoint on
cross-origin iframes. An attacker could potentially exploit this to
steal confidential imformation. (CVE-2014-1483)

Frederik Braun discovered that the CSP implementation in Firefox did
not handle XSLT stylesheets in accordance with the specification,
potentially resulting in unexpected script execution in some
circumstances (CVE-2014-1485)

Arthur Gerkis discovered a use-after-free in Firefox. An attacker
could potentially exploit this to cause a denial of service via
application crash, or execute arbitrary code with the priviliges of
the user invoking Firefox. (CVE-2014-1486)

Masato Kinugawa discovered a cross-origin information leak in web
worker error messages. An attacker could potentially exploit this to
steal confidential information. (CVE-2014-1487)

Yazan Tommalieh discovered that web pages could activate buttons on
the default Firefox startpage (about:home) in some circumstances. An
attacker could potentially exploit this to cause data loss by
triggering a session restore. (CVE-2014-1489)

Soeren Balko discovered a crash in Firefox when terminating web
workers running asm.js code in some circumstances. An attacker could
potentially exploit this to execute arbitrary code with the priviliges
of the user invoking Firefox. (CVE-2014-1488)

Several issues were discovered with ticket handling in NSS. An
attacker could potentially exploit these to cause a denial of service
or bypass cryptographic protection mechanisms. (CVE-2014-1490,
CVE-2014-1491)

Boris Zbarsky discovered that security restrictions on window objects
could be bypassed under certain circumstances. (CVE-2014-1481).

Solution :

Update the affected firefox package.
