"According to the versions of the cups package installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :

  - OpenPrinting CUPS is an open source printing system. In versions 2.4.2 and prior, a heap buffer overflow
    vulnerability would allow a remote attacker to launch a denial of service (DoS) attack. A buffer overflow
    vulnerability in the function `format_log_line` could allow remote attackers to cause a DoS on the
    affected system. Exploitation of the vulnerability can be triggered when the configuration file
    `cupsd.conf` sets the value of `loglevel `to `DEBUG`. No known patches or workarounds exist at time of
    publication. (CVE-2023-32324)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
