libruby3.3: Net::IMAP implements Internet Message Access Protocol (IMAP) clientfunctionality in Ruby

Net::IMAP implements Internet Message Access Protocol (IMAP) clientfunctionality in Ruby. Starting in version 0.3.2 and prior to versions0.3.8, 0.4.19, and 0.5.6, there is a possibility for denial of service bymemory exhaustion in `net-imap`'s response parser. At any time while theclient is connected, a malicious server can send can send highlycompressed `uid-set` data which is automatically read by the client'sreceiver thread. The response parser uses `Range#to_a` to convert the`uid-set` data into arrays of integers, with no limitation on the expandedsize of the ranges. Versions 0.3.8, 0.4.19, 0.5.6, and higher fix thisissue. Additional details for proper configuration of fixed versions andbackward compatibility are available in the GitHub Security Advisory.
