Synopsis
Moderate: thunderbird security update
Type/Severity
Security Advisory: Moderate
Topic
Updated thunderbird packages that fix several security issues are now
available for Red Hat Enterprise Linux 4 and 5.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
Description
Mozilla Thunderbird is a standalone mail and newsgroup client.
Several flaws were found in the processing of malformed HTML mail content.
An HTML mail message containing malicious content could cause Thunderbird
to crash or, potentially, execute arbitrary code as the user running
Thunderbird. (CVE-2008-0016, CVE-2008-4058, CVE-2008-4059, CVE-2008-4060,
CVE-2008-4061, CVE-2008-4062)
Several flaws were found in the way malformed HTML mail content was
displayed. An HTML mail message containing specially crafted content could
potentially trick a Thunderbird user into surrendering sensitive
information. (CVE-2008-3835, CVE-2008-4067, CVE-2008-4068)
A flaw was found in Thunderbird that caused certain characters to be
stripped from JavaScript code. This flaw could allow malicious JavaScript
to bypass or evade script filters. (CVE-2008-4065, CVE-2008-4066)
Note: JavaScript support is disabled by default in Thunderbird; the above
issue is not exploitable unless JavaScript is enabled.
A heap based buffer overflow flaw was found in the handling of cancelled
newsgroup messages. If the user cancels a specially crafted newsgroup
message it could cause Thunderbird to crash or, potentially, execute
arbitrary code as the user running Thunderbird. (CVE-2008-4070)
All Thunderbird users should upgrade to these updated packages, which
resolve these issues.
