[dependabot]

Bumps net-imap from 0.3.1 to 0.4.24.

Release notes

Sourced from net-imap's releases.

v0.4.24

[!IMPORTANT] The 0.4.x release branch will only receive critical security fixes, and will be unsupported when ruby 3.3 is EOL. Please upgrade to a newer version.

What's Changed

🔒 Security

This release contains fixes for multiple vulnerabilities concerning STARTTLS stripping, argument validation, and denial of service attacks.

[!WARNING] ruby/net-imap#666 fixes a STARTTLS stripping vulnerability (GHSA-vcgp-9326-pqcp). Without this fix, a man-in-the-middle attacker can cause Net::IMAP#starttls to return "successfully", without starting TLS.

[!IMPORTANT] Argument validation is significantly improved. Several injection vulnerabilities have been fixed: ruby/net-imap#663 fixes CRLF/command/argument injection via Symbol arguments (GHSA-75xq-5h9v-w6px). ruby/net-imap#663 fixes CRLF/command/argument injection via the attr argument to #store/#uid_store (GHSA-hm49-wcqc-g2xg) ruby/net-imap#663 fixes CRLF/command/argument injection via the storage_limit argument to #setquota (GHSA-hm49-wcqc-g2xg). ruby/net-imap#663 fixes CRLF/command injection via RawData (GHSA-hm49-wcqc-g2xg):

• #search and #uid_search send criteria as raw data, when it is a String
• #fetch and #uid_fetch send attr as raw data, when it is a String. When attr is an Array, its String members are sent as raw data.

[!CAUTION] RawData does not defend against other forms of argument injection! It is an intentionally low-level API.

[!NOTE] Two denial of service vulnerabilities have been addressed. These are generally only relevant when connecting to an untrusted hostile server (or without TLS).

ruby/net-imap#651 fixes quadratic time complexity when reading large responses containing many string literals (GHSA-q2mw-fvj9-vvcw). ruby/net-imap#655 adds a configurable max_iterations count for SCRAM-* authentication (GHSA-87pf-fpwv-p7m7).

The default ScramAuthenticator#max_iterations is 2**31 - 1 (max 32-bit signed int), which was already OpenSSL's maximum value. It provides no protection against hostile servers unless it is explicitly set to a lower value by the user.
