ruby: net-imap: Net::IMAP: Denial of Service via crafted IMAP responses
A flaw was found in Net::IMAP, a Ruby library implementing the Internet Message Access Protocol IMAP client functionality. A hostile server can exploit a quadratic time complexity issue in the Net::IMAP::ResponseReader when processing large responses containing numerous string literals. This can...
net-imap: ruby: Net::IMAP: Information disclosure via man-in-the-middle attack bypassing TLS
A flaw was found in the Ruby net-imap library. When upgrading a cleartext IMAP connection to TLS using the Net::IMAPstarttls 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...
