Due to lack of proper input scrubbing, curl could pass on user name and telnet options to the server as provided, contrary to expectations. (CVE-2023-27533) Harry Sintonen discovered that curl incorrectly handled special tilde characters when used with SFTP paths. A remote attacker could possibly use this issue to circumvent filtering.

(CVE-2023-27535) Harry Sintonen discovered that curl incorrectly reused connections when the GSS delegation option had been changed. This could lead to the option being reused, contrary to expectations. (CVE-2023-27536) Harry Sintonen discovered that curl incorrectly reused certain SSH connections. This could lead to the wrong credentials being reused, contrary to expectations. (CVE-2023-27538) Update Instructions: Run `sudo pro fix USN-5964-1` to fix the vulnerability.
