| Description: | Summary:
The remote host is missing an update for the 'mozilla-thunderbird, thunderbird' package(s) announced via the USN-629-1 advisory.
Vulnerability 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.
