✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Ensure the spell checker is turned off by running :set nospell within Vim. Do not open untrusted or suspicious files—particularly those encrypted with libsodium methods (VimCrypt~04! or VimCrypt~05!)—within the Vim editor. This prevents the execution of the vulnerable decryption routine Workaround: To mitigate this issue disable spell checking or avoid using SOFO-based spell files. This can be achieved globally by adding set nospell to your ~/.vimrc configuration file. Ensure your systems utilize standard UTF-8 encoding. This flaw is strictly confined to legacy 8-bit encodings and cannot be triggered under default Red Hat configurations.
