Mozilla Thunderbird is a standalone mail and newsgroup client.

(CVE-2006-4565, CVE-2006-4566)

A flaw was found in the Thunderbird auto-update verification system.
An attacker who has the ability to spoof a victim's DNS could get Firefox to download and install malicious code. In order to exploit this issue an attacker would also need to get a victim to previously accept an unverifiable certificate. (CVE-2006-4567)

A flaw was found in the handling of JavaScript timed events. A malicious HTML email could crash the browser or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-4253)

Daniel Bleichenbacher recently described an implementation error in RSA signature verification. For RSA keys with exponent 3 it is possible for an attacker to forge a signature that which would be incorrectly verified by the NSS library. (CVE-2006-4340)

A flaw was found in Thunderbird that triggered when a HTML message contained a remote image pointing to a XBL script. An attacker could have created a carefully crafted message which would execute JavaScript if certain actions were performed on the email by the recipient, even if JavaScript was disabled. (CVE-2006-4570)

A number of flaws were found in Thunderbird. A malicious HTML email could cause a crash or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-4571)
