New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Red Hat host is missing a security update.
DescriptionUpdated thunderbird packages that fix several security bugs are now available for Red Hat Enterprise Linux 4.
This update has been rated as having critical security impact by the Red Hat Security Response Team.
[Updated 06 March 2007] Updated text description to add CVE-2007-1282 and remove CVE-2007-0994, which was mistakenly listed as affecting Thunderbird. No changes have been made to these erratum packages.
Mozilla Thunderbird is a standalone mail and newsgroup client.
(CVE-2007-0775, CVE-2007-0777, CVE-2007-1092)
A flaw was found in the way Thunderbird processed text/enhanced and text/richtext formatted mail message. A specially crafted mail message could execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2007-1282)
Several cross-site scripting (XSS) flaws were found in the way Thunderbird processed certain malformed HTML mail messages. A malicious HTML mail message could display misleading information which may result in a user unknowingly divulging sensitive information such as a password. (CVE-2006-6077, CVE-2007-0995, CVE-2007-0996)
A flaw was found in the way Thunderbird cached web content on the local disk. A malicious HTML mail message may be able to inject arbitrary HTML into a browsing session if the user reloads a targeted site. (CVE-2007-0778)
A flaw was found in the way Thunderbird displayed certain web content.
A malicious HTML mail message could generate content which could overlay user interface elements such as the hostname and security indicators, tricking a user into thinking they are visiting a different site. (CVE-2007-0779)
Two flaws were found in the way Thunderbird displayed blocked popup windows. If a user can be convinced to open a blocked popup, it is possible to read arbitrary local files, or conduct an XSS attack against the user. (CVE-2007-0780, CVE-2007-0800)
Two buffer overflow flaws were found in the Network Security Services (NSS) code for processing the SSLv2 protocol. Connecting to a malicious secure web server could cause the execution of arbitrary code as the user running Thunderbird. (CVE-2007-0008, CVE-2007-0009)
A flaw was found in the way Thunderbird handled the 'location.hostname' value during certain browser domain checks. This flaw could allow a malicious HTML mail message to set domain cookies for an arbitrary site, or possibly perform an XSS attack.
Users of Thunderbird are advised to apply this update, which contains Thunderbird version 184.108.40.206 that corrects these issues.
SolutionUpdate the affected thunderbird package.
