Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the python-ldap package installed, the EulerOS Virtualization 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)
