3. Problem description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

Two flaws were found in the way Thunderbird processed certain regular
expressions. A malicious HTML email could cause a crash or possibly
execute arbitrary code as the user running Thunderbird. (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)

Users of Thunderbird are advised to upgrade to this update, which contains
Thunderbird version 1.5.0.7 that corrects these issues.
