Ubuntu Security Notice (C) 2011-2013 Canonical, Inc. / NASL script (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

Gary Kwong, Igor Bukanov, and Bob Clary discovered multiple memory
vulnerabilities in the browser rendering engine. An attacker could use
these to possibly execute arbitrary code with the privileges of the
user invoking Firefox. (CVE-2011-2982)

It was discovered that a vulnerability in event management code could
permit JavaScript to be run in the wrong context. This could
potentially allow a malicious website to run code as another website
or with escalated privileges within the browser. (CVE-2011-2981)

It was discovered that an SVG text manipulation routine contained a
dangling pointer vulnerability. An attacker could potentially use this
to crash Firefox or execute arbitrary code with the privileges of the
user invoking Firefox. (CVE-2011-0084)

It was discovered that web content could receive chrome privileges if
it registered for drop events and a browser tab element was dropped
into the content area. This could potentially allow a malicious
website to run code with escalated privileges within the browser.
(CVE-2011-2984)

It was discovered that appendChild contained a dangling pointer
vulnerability. An attacker could potentially use this to crash Firefox
or execute arbitrary code with the privileges of the user invoking
Firefox. (CVE-2011-2378)

It was discovered that data from other domains could be read when
RegExp.input was set. This could potentially allow a malicious website
access to private data from other domains. (CVE-2011-2983).
