SynopsisThe remote Windows host contains a mail client that is affected by a remote code execution vulnerability.
DescriptionThe version of Mozilla Thunderbird installed on the remote Windows host is prior to 45.5.1. It is, therefore, affected by a use-after-free error in dom/smil/nsSMILTimeContainer.cpp when handling SVG animations. An unauthenticated, remote attacker can exploit this issue, via a specially crafted web page, to deference already freed memory, resulting in the execution of arbitrary code.
SolutionUpgrade to Mozilla Thunderbird version 45.5.1 or later.
