Vulnerability identifier: #VU52375
Vulnerability risk: Low
Exploitation vector: Local
Exploit availability: No
The 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.
Vulnerable software versions
Mozilla Thunderbird: 78.0 - 78.9.0, 68.0 - 68.12.1, 60.0 - 60.9.1
