What to do

AI-suggested

A security update for curl has been released that fixes all listed vulnerabilities. Users and administrators should apply this update promptly to mitigate the risks. Since this is a traditional software update and not a cloud service, manual patching is required. No additional mitigation steps are specified beyond applying the update.

Description

This security update for curl addresses multiple vulnerabilities including incomplete mutual TLS configuration matching, cross-origin Digest authentication state leaks, SSH verification bypass, and several others affecting protocols like IMAP, FTP, TFTP, and SFTP. The update fixes issues that could lead to credential leaks, command injection, stack overflow, and improper host verification. These vulnerabilities collectively pose a high security risk if left unpatched.
