Ubuntu 8.04 LTS / 9.10 / 10.04 LTS / 10.10 : firefox, firefox-{3.0,3.5}, xulrunner-1.9.{1,2} vulnerabilities (USN-1019-1)

Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

Jesse Ruderman, Andreas Gal, Nils, Brian Hackett, and Igor Bukanov
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-2010-3776, CVE-2010-3777,
CVE-2010-3778)

It was discovered that Firefox did not properly verify the about:blank
location elements when it was opened via window.open(). An attacker
could exploit this to run arbitrary code with chrome privileges.
(CVE-2010-3771)

It was discovered that Firefox did not properly handle &lt
div&gt

elements when processing a XUL tree. If a user were tricked into
opening a malicious web page, an attacker could exploit this to crash
the browser or possibly run arbitrary code as the user invoking the
program. (CVE-2010-3772)

Marc Schoenefeld and Christoph Diehl discovered several problems when
handling downloadable fonts. The new OTS font sanitizing library was
added to mitigate these issues. (CVE-2010-3768)

Gregory Fleischer discovered that the Java LiveConnect script could be
made to run in the wrong security context. An attacker could exploit
this to read local files and run arbitrary code as the user invoking
the program. (CVE-2010-3775)

Several problems were discovered in the JavaScript engine. If a user
were tricked into opening a malicious web page, an attacker could
exploit this to crash the browser or possibly run arbitrary code as
the user invoking the program. (CVE-2010-3766, CVE-2010-3767,
CVE-2010-3773)

Michal Zalewski discovered that Firefox did not always properly handle
displaying pages from network or certificate errors. An attacker could
exploit this to spoof the location bar, such as in a phishing attack.
(CVE-2010-3774)

Yosuke Hasegawa and Masatoshi Kimura discovered that several character
encodings would have some characters converted to angle brackets. An
attacker could utilize this to perform cross-site scripting attacks.
(CVE-2010-3770).

Solution :

Update the affected packages.
