Ubuntu Security Notice USN-5393-1
Ubuntu Security Notice 5393-1 - 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. 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.
