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.
