Software description

Details

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

It was discovered that the XPCSafeJSObjectWrapper (SJOW) security wrapper
did not always honor the same-origin policy. If JavaScript was enabled, an
attacker could exploit this to run untrusted JavaScript from other domains.
(CVE-2010-2763)

Matt Haggard discovered that Thunderbird 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 Thunderbird processed the
HTML frameset element. If a user were tricked into viewing a malicious
site, a remote attacker could use this to crash Thunderbird 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 Thunderbird 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. If JavaScript was enabled, an attacker could utilize this to
perform cross-site scripting attacks. (CVE-2010-2769)

A buffer overflow was discovered in Thunderbird when processing text runs.
If a user were tricked into viewing a malicious site, a remote attacker
could use this to crash Thunderbird 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 Thunderbird or possibly run
arbitrary code as the user invoking the program. (CVE-2010-3169)
