Thunderbird allowed the Text Direction Override Unicode Character in
filenames. An email attachment could be incorrectly shown as being a
document file, while in fact it was an executable file. Newer versions of
Thunderbird will strip the character and show the correct file extension.
This vulnerability affects Thunderbird < 115.0.1 and Thunderbird <
102.13.1.
