Title
net-imap vulnerable to STARTTLS stripping via invalid response timing
Summary
Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to versions 0.3.10, 0.4.24, 0.5.14, and 0.6.4, a man-in-the-middle attacker can cause Net::IMAP#starttls to return "successfully", without starting TLS. This issue has been patched in versions 0.3.10, 0.4.24, 0.5.14, and 0.6.4.

"value": "A flaw was found in the Ruby net-imap library. When upgrading a cleartext IMAP connection to TLS using the Net::IMAP#starttls method, the library improperly handles certain responses received during STARTTLS negotiation. A man-in-the-middle (MITM) attacker can inject a predicted tagged OK response before the client completes the STARTTLS command, causing the operation to appear successful without establishing a TLS session. As a result, the connection may continue to transmit sensitive information in cleartext and enable modification of data exchanged over the affected connection, while the application incorrectly believes that encryption has been enabled."

Title
Mastodon: Insufficient verification of email addresses
Summary
Mastodon is a free, open-source social network server based on ActivityPub. Prior to v4.5.9, v4.4.16, and v4.3.22, Mastodon allows restricting new user sign-up based on e-mail domain names, and performs basic validation on e-mail addresses, but fails to restrict characters that are interpreted differently by some mailing servers. This vulnerability is fixed in v4.5.9, v4.4.16, and v4.3.22.

Title
Botan has a TLS 1.3 certificate authentication bypass
Summary
Botan is a C++ cryptography library. Prior to version 3.11.1, the TLS 1.3 implementation allowed ApplicationData records to be processed prior to the Finished message being received. A server which is attempting to enforce client authentication via certificates can by bypassed by a client which entirely omits Certificate, CertificateVerify, and the Finished message and instead sends application data records. This vulnerability is fixed in 3.11.1.
