thunderbird vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 21.10 – Ubuntu 20.04 LTS – Ubuntu 18.04 LTS
Several security issues were fixed in Thunderbird.
Software Description: – thunderbird: Mozilla Open Source mail and newsgroup client
Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, conduct spoofing attacks, or execute arbitrary code. (CVE-2022-1097, CVE-2022-1196, CVE-2022-28281, CVE-2022-28282, CVE-2022-28285, CVE-2022-28286, CVE-2022-28289)
It was discovered that Thunderbird ignored OpenPGP revocation when importing a revoked key in some circumstances. An attacker could potentially exploit this by tricking the user into trusting the authenticity of a message or tricking them into use a revoked key to send an encrypted message. (CVE-2022-1197)
