摘要:
The signature of a digitally signed S/MIME email message may optionally specify the signature creation date and time. If present, Thunderbird did not compare the signature creation date with the message date and time, and displayed a valid signature despite a date or time mismatch. This could be used to give recipients the impression that a message was sent at a different date or time. This vulnerability affects Thunderbird < 115.6.

经数字签名的S/MIME电子邮件消息中,签名可选择性包含签名创建日期和时间信息。若存在该信息,Thunderbird此前未将签名创建日期与消息日期进行比对,即使日期或时间不匹配仍显示为有效签名。该漏洞可能被利用,使收件人对邮件实际发送日期产生误判。此漏洞影响Thunderbird < 115.6版本。
