| Description: | Mozilla Thunderbird is a standalone mail and newsgroup client.
Several flaws were found in the way Thunderbird processes certain malformed Javascript code. A malicious web page could cause the execution of Javascript code in such a way that could cause Thunderbird to crash or execute arbitrary code as the user running Thunderbird. JavaScript support is disabled by default in Thunderbird; this issue is not exploitable without enabling JavaScript. (CVE-2006-6498, CVE-2006-6501, CVE-2006-6502, CVE-2006-6503, CVE-2006-6504)
Several flaws were found in the way Thunderbird renders web pages. A malicious web page could cause the browser to crash or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-6497)
A heap based buffer overflow flaw was found in the way Thunderbird parses the Content-Type mail header. A malicious mail message could cause the Thunderbird client to crash or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-6505)
Users of Thunderbird are advised to apply this update, which contains Thunderbird version 1.5.0.9 that corrects these issues.
