The remote Ubuntu host is missing a security-related patch.
Benjamin Smedberg, Bob Clary, Jesse Ruderman, and Josh Aas discovered
multiple memory vulnerabilities in the Gecko rendering engine. An
attacker could use these to possibly execute arbitrary code with the
privileges of the user invoking Thunderbird. (CVE-2011-2995,
Boris Zbarsky discovered that a frame named 'location' could shadow
the window.location object unless a script in a page grabbed a
reference to the true object before the frame was created. This is in
violation of the Same Origin Policy. A malicious E-Mail could possibly
use this to access the local file system. (CVE-2011-2999)
Mark Kaplan discovered an integer underflow in the SpiderMonkey
Ian Graham discovered that when multiple Location headers were
present, Thunderbird would use the second one resulting in a possible
CRLF injection attack. CRLF injection issues can result in a wide
variety of attacks, such as XSS (Cross-Site Scripting)
vulnerabilities, browser cache poisoning, and cookie theft.
Mariusz Mlynski discovered that if the user could be convinced to hold
down the enter key, a malicious website or E-Mail could potential pop
up a download dialog and the default open action would be selected.
This would result in potentially malicious content being run with
privileges of the user invoking Thunderbird. (CVE-2011-2372).
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.
