According to the versions of the python-ldap packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - python-ldap before 3.4.0 is vulnerable to a denial of service when ldap.schema is used for untrusted     schema definitions, because of a regular expression denial of service (ReDoS) flaw in the LDAP schema     parser. By sending crafted regex input, a remote authenticated attacker could exploit this vulnerability     to cause a denial of service condition. (CVE-2021-46823)

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.
