Insight
Various flaws were discovered in the browser engine. If a user had Javascript enabled and were tricked into opening a malicious web page, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-2798, CVE-2008-2799)
It was discovered that Thunderbird would allow non-privileged XUL documents to load chrome scripts from the fastload file if Javascript was enabled. This could allow an attacker to execute arbitrary Javascript code with chrome privileges. (CVE-2008-2802)
A flaw was discovered in Thunderbird that allowed overwriting trusted objects via mozIJSSubScriptLoader.loadSubScript(). If a user had Javascript enabled and was tricked into opening a malicious web page, an attacker could execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-2803)
Daniel Glazman found that an improperly encoded .properties file in an add-on can result in uninitialized memory being used. If a user were tricked into installing a malicious add-on, Thunderbird may be able to see data from other programs. (CVE-2008-2807)
John G. Myers discovered a weakness in the trust model used by Thunderbird regarding alternate names on self-signed certificates.
If a user were tricked into accepting a certificate containing alternate name entries, an attacker could impersonate another server. (CVE-2008-2809)
A vulnerability was discovered in the block reflow code of Thunderbird. If a user enabled Javascript, this vulnerability could be used by an attacker to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-2811)
A flaw was discovered in the browser engine. A variable could be made to overflow causing Thunderbird to crash. If a user enable Javascript and was tricked into opening a malicious web page, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-2785)
Mozilla developers audited the MIME handling code looking for similar vulnerabilities to the previously fixed CVE-2008-0304, and changed several function calls to use safer versions of string routines.
