Summary

Mozilla Thunderbird, the email and news client, is affected by this vulnerability. Clicking a crafted news: or snews: link can make it connect to arbitrary servers and send unintended commands to services on the user's network, and snews: links may connect without encryption.

Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.

Read the original description

Clicking a news: or snews: link that referenced a message-ID made Thunderbird connect, without asking, to the host and port given in the link, even if it was not a configured news server. Line breaks in the message-ID were sent to the server unmodified, so a crafted link could send arbitrary commands to services reachable from the user's network. In addition, snews: links to such servers connected without TLS. This vulnerability was fixed in Thunderbird 159 and Thunderbird 153.6.
