Astra Linux – Vulnerability in Thunderbird

An attacker may carry out a DoS attack to prevent a user from sending encrypted emails to a correspondent. If an attacker creates a crafted OpenPGP key with a subkey that has an invalid self-signature, and the Thunderbird user imports the crafted key, then Thunderbird may attempt to use the inval...

Astra Linux – Vulnerability in Thunderbird

An OpenPGP digital signature includes information about the date when the signature was created. When displaying an email that contains a digital signature, the email’s date will be displayed. If the dates are different, then Thunderbird does not report the email as having an invalid signature. I...

Astra Linux – Vulnerability in Thunderbird

When a user explicitly requested Thunderbird to decrypt an inline OpenPGP message that was embedded in a text section of an email, which was formatted and styled using HTML and CSS, the decrypted contents were displayed in a context where the CSS styles from the outer messages remained active. If...

Astra Linux – Vulnerability in opensc
