thunderbird security update

CentOS Errata and Security Advisory CESA-2008:0105

Mozilla Thunderbird is a standalone mail and newsgroup client.

A heap-based buffer overflow flaw was found in the way Thunderbird
processed messages with external-body Multipurpose Internet Message
Extensions (MIME) types. A HTML mail message containing malicious content
could cause Thunderbird to execute arbitrary code as the user running
Thunderbird. (CVE-2008-0304)

Several flaws were found in the way Thunderbird processed certain malformed
HTML mail content. A HTML mail message containing malicious content could
cause Thunderbird to crash, or potentially execute arbitrary code as the
user running Thunderbird. (CVE-2008-0412, CVE-2008-0413, CVE-2008-0415,
CVE-2008-0419)

Several flaws were found in the way Thunderbird displayed malformed HTML
mail content. A HTML mail message containing specially-crafted content
could trick a user into surrendering sensitive information. (CVE-2008-0420,
CVE-2008-0591, CVE-2008-0593)

A flaw was found in the way Thunderbird handles certain chrome URLs. If a
user has certain extensions installed, it could allow a malicious HTML mail
message to steal sensitive session data. Note: this flaw does not affect a
default installation of Thunderbird. (CVE-2008-0418)

Note: JavaScript support is disabled by default in Thunderbird; the above
issues are not exploitable unless JavaScript is enabled.

A flaw was found in the way Thunderbird saves certain text files. If a
remote site offers a file of type “plain/text”, rather than “text/plain”,
Thunderbird will not show future “text/plain” content to the user, forcing
them to save those files locally to view the content. (CVE-2008-0592)

Users of thunderbird are advised to upgrade to these updated packages,
which contain backported patches to resolve these issues.
