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

If a Thunderbird user has previously imported Alice’s OpenPGP key, and Alice has extended the validity period of her key, but Alice’s updated key has not yet been imported, an attacker may send an email containing a crafted version of Alice’s key with an invalid subkey. In this case, Thunderbird...
