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 lead to the client's CPU being exhausted, resulting in a denial of service (DoS) attack.
