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

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

use this to gather information about servers on internal private networks.
(CVE-2010-2764)

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)
