Ubuntu 8.04 LTS / 8.10 / 9.04 : thunderbird vulnerabilities (USN-782-1)

high Nessus Plugin ID 39533


The remote Ubuntu host is missing one or more security-related patches.


Several flaws were discovered in the JavaScript engine of Thunderbird.
If a user had JavaScript enabled and were tricked into viewing malicious web content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-1303, CVE-2009-1305, CVE-2009-1392, CVE-2009-1833, CVE-2009-1838)

Several flaws were discovered in the way Thunderbird processed malformed URI schemes. If a user were tricked into viewing a malicious website and had JavaScript and plugins enabled, a remote attacker could execute arbitrary JavaScript or steal private data.
(CVE-2009-1306, CVE-2009-1307, CVE-2009-1309)

Cefn Hoile discovered Thunderbird did not adequately protect against embedded third-party stylesheets. If JavaScript were enabled, an attacker could exploit this to perform script injection attacks using XBL bindings. (CVE-2009-1308)

Shuo Chen, Ziqing Mao, Yi-Min Wang, and Ming Zhang discovered that Thunderbird did not properly handle error responses when connecting to a proxy server. If a user had JavaScript enabled while using Thunderbird to view websites and a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. (CVE-2009-1836)

It was discovered that Thunderbird could be made to run scripts with elevated privileges. If a user had JavaScript enabled while having certain non-default add-ons installed and were tricked into viewing a malicious website, an attacker could cause a chrome privileged object, such as the browser sidebar, to run arbitrary code via interactions with the attacker controlled website. (CVE-2009-1841).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
