Details

Several flaws were discovered in the JavaScript engine of Thunderbird. If a
user had JavaScript enabled and were tricked into viewing malicious web
content, a remote attacker could cause a denial of service or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2009-0689, CVE-2009-2463, CVE-2009-3075)

Josh Soref discovered that the BinHex decoder used in Thunderbird contained
a flaw. If a user were tricked into viewing malicious content, a remote
attacker could cause a denial of service or possibly execute arbitrary code
with the privileges of the user invoking the program. (CVE-2009-3072)

It was discovered that Thunderbird did not properly manage memory when
using XUL tree elements. If a user were tricked into viewing malicious
content, a remote attacker could cause a denial of service or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2009-3077)

Jesse Ruderman and Sid Stamm discovered that Thunderbird did not properly
display filenames containing right-to-left (RTL) override characters. If a
user were tricked into opening a malicious file with a crafted filename, an
attacker could exploit this to trick the user into opening a different file
than the user expected. (CVE-2009-3376)

Takehiro Takahashi discovered flaws in the NTLM implementation in
Thunderbird. If an NTLM authenticated user opened content containing links
to a malicious website, a remote attacker could send requests to other
applications, authenticated as the user. (CVE-2009-3983)

Ludovic Hirlimann discovered a flaw in the way Thunderbird indexed certain
messages with attachments. A remote attacker could send specially crafted
content and cause a denial of service or possibly execute arbitrary code
with the privileges of the user invoking the program. (CVE-2010-0163)
