CVE-ID: CVE-2021-29950
CWE-ID:
CWE-312 - Cleartext Storage of Sensitive Information
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to the way Thunderbird handles secret OpenPGP keys. The application unprotects a secret OpenPGP key prior to using it for a decryption,
signing or key import task. If the task runs into a failure, the secret
key may remain in memory in its unprotected state. A local user or malicious application can read the key and use it to decrypt email messages.
Install updates from vendor's website.
