Bump net-imap from 0.4.1 to 0.4.20

Open dependabot[bot] opened this issue 7 months ago • 0 comments

Bumps net-imap from 0.4.1 to 0.4.20.

Release notes

Sourced from net-imap's releases.

v0.4.20

What's Changed

This release backports two features to prevent unbounded memory use: the response_handlers keyword argument to Net::IMAP.new so response handlers can be added before the server can send any responses (ruby/net-imap#427), and the max_response_size config attribute (ruby/net-imap#445).

[!NOTE] The default max_response_size is nil (unlimited), to avoid backward compatibility issues with secure connections to trusted servers that are well-behaved. It can be configured more conservatively to guard against untrusted servers (for example, connecting to user-provided hostnames). It is the responsibility of net-imap users to configure their client appropriately for the server they are connecting to.

v0.4.19

What's Changed

🔒 Security Fix

Fixes CVE-2025-25186 (GHSA-7fc5-f82f-cx69): A malicious server can exhaust client memory by sending APPENDUID or COPYUID responses with very large uid-set ranges. Net::IMAP::UIDPlusData expands these ranges into arrays of integers.

Fix with minor API changes

Set config.parser_use_deprecated_uidplus_data to false to replace UIDPlusData with AppendUIDData and CopyUIDData. These classes store their UIDs as Net::IMAP::SequenceSet objects (not expanded into arrays of integers). Code that does not handle APPENDUID or COPYUID responses should not see any difference. Code that does handle these responses may need to be updated.

For v0.3.8, this option is not available For v0.4.19, the default value is true. For v0.5.6, the default value is :up_to_max_size. For v0.6.0, the only allowed value will be false (UIDPlusData will be removed from v0.6).
