Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Jesse Ruderman, Igor Bukanov, Olli Pettay, Gary Kwong, Jeff Walden,
Henry Sivonen, Martijn Wargers, David Baron and Marcia Knous
discovered several memory issues in the browser engine. An attacker
could exploit these to crash the browser or possibly run arbitrary
code as the user invoking the program. (CVE-2011-0053, CVE-2011-0062)

Zach Hoffman discovered that a recursive call to eval() wrapped in a
try/catch statement places the browser into a inconsistent state. An
attacker could exploit this to force a user to accept any dialog.
(CVE-2011-0051)

It was discovered that memory was used after being freed in a method
used by JSON.stringify. An attacker could exploit this to crash the
browser or possibly run arbitrary code as the user invoking the
program. (CVE-2011-0055)

Christian Holler discovered multiple buffer overflows in the
JavaScript engine. An attacker could exploit these to crash the
browser or possibly run arbitrary code as the user invoking the
program. (CVE-2011-0054, CVE-2011-0056)

Daniel Kozlowski discovered that a JavaScript Worker kept a reference
to memory after it was freed. An attacker could exploit this to crash
the browser or possibly run arbitrary code as the user invoking the
program. (CVE-2011-0057)

Alex Miller discovered a buffer overflow in the browser rendering
engine. An attacker could exploit this to crash the browser or
possibly run arbitrary code as the user invoking the program.
(CVE-2011-0058)

Roberto Suggi Liverani discovered a possible issue with unsafe
JavaScript execution in chrome documents. A malicious extension could
exploit this to execute arbitrary code with chrome privlieges.
(CVE-2010-1585)

Jordi Chancel discovered a buffer overlow in the JPEG decoding engine.
An attacker could exploit this to crash the browser or possibly run
arbitrary code as the user invoking the program. (CVE-2011-0061)

Peleus Uhley discovered a CSRF vulnerability in the plugin code
related to 307 redirects. This could allow custom headers to be
forwarded across origins. (CVE-2011-0059).

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 packages.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 8.7
(CVSS2#E:ND/RL:OF/RC:C)
