Details

connection options. 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-2023-27534)

Harry Sintonen discovered that curl incorrectly reused certain FTP
connections. This could lead to the wrong credentials being reused,
contrary to expectations. (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)
