Description :

USN-975-1 fixed vulnerabilities in Firefox and Xulrunner. Some users
reported stability problems under certain circumstances. This update
fixes the problem.

We apologize for the inconvenience.

Several dangling pointer vulnerabilities were discovered in Firefox.
An attacker could exploit this to crash the browser or possibly run
arbitrary code as the user invoking the program. (CVE-2010-2760,
CVE-2010-2767, CVE-2010-3167)

Blake Kaplan and Michal Zalewski discovered several
weaknesses in the XPCSafeJSObjectWrapper (SJOW) security
wrapper. If a user were tricked into viewing a malicious
site, a remote attacker could use this to run arbitrary
JavaScript with chrome privileges. (CVE-2010-2762)

Matt Haggard discovered that Firefox did not honor
same-origin policy when processing the statusText property
of an XMLHttpRequest object. If a user were tricked into
viewing a malicious site, a remote attacker could use this
to gather information about servers on internal private
networks. (CVE-2010-2764)

Chris Rohlf discovered an integer overflow when Firefox
processed the HTML frameset element. If a user were tricked
into viewing a malicious site, a remote attacker could use
this to crash the browser or possibly run arbitrary code as
the user invoking the program. (CVE-2010-2765)

Several issues were discovered in the browser engine. If a
user were tricked into viewing a malicious site, a remote
attacker could use this to crash the browser or possibly run
arbitrary code as the user invoking the program.
(CVE-2010-2766, CVE-2010-3168)

David Huang and Collin Jackson discovered that the <object>
tag could override the charset of a framed HTML document in
another origin. An attacker could utilize this to perform
cross-site scripting attacks. (CVE-2010-2768)

Paul Stone discovered that with designMode enabled an HTML
selection containing JavaScript could be copied and pasted
into a document and have the JavaScript execute within the
context of the site where the code was dropped. An attacker
could utilize this to perform cross-site scripting attacks.
(CVE-2010-2769)

A buffer overflow was discovered in Firefox when processing
text runs. If a user were tricked into viewing a malicious
site, a remote attacker could use this to crash the browser
or possibly run arbitrary code as the user invoking the
program. (CVE-2010-3166)

Peter Van der Beken, Jason Oster, Jesse Ruderman, Igor
Bukanov, Jeff Walden, Gary Kwong and Olli Pettay discovered
several flaws in the browser engine. If a user were tricked
into viewing a malicious site, a remote attacker could use
this to crash the browser or possibly run arbitrary code as
the user invoking the program. (CVE-2010-3169).
