Mozilla has released a Security Advisory on March 28, 2023, in which it addressed a vulnerability in the Thunderbird email client. The affected version of Thunderbird is any version before 102.9.1. The vulnerability specifically targeted Thunderbird users who use the Matrix chat protocol and could have allowed for a denial-of-service attack.
The Cyber Centre has urged both users and administrators to review the web links provided by Mozilla and apply any necessary updates.
This is an essential step for ensuring system security and to avoid being targeted by cyber attackers.
Mozilla Thunderbird is an open-source email client that is widely used by people worldwide. The Matrix chat protocol, which was found to be vulnerable to this attack, is an open network for secure, decentralized communication.
