RHEL 4 / 5 : thunderbird (RHSA-2008:0908)
Critical Nessus Plugin ID 34330
SynopsisThe remote Red Hat host is missing a security update.
DescriptionUpdated 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.
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 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.
All Thunderbird users should upgrade to these updated packages, which resolve these issues.
SolutionUpdate the affected thunderbird package.
