- 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)
