high Nessus Plugin ID 173037

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5964-1 advisory.

 Harry Sintonen discovered that curl incorrectly handled certain TELNET 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
