An update for python-ldap is now available for openEuler-20.03-LTS-SP1 and openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1792 Final 1.0 1.0 2022-07-30 Initial 2022-07-30 2022-07-30 openEuler SA Tool V1.0 2022-07-30 python-ldap security update An update for python-ldap is now available for openEuler-20.03-LTS-SP1 and openEuler-22.03-LTS. python-ldap provides an object-oriented API for working with LDAP within Python programs. It allows access to LDAP directory servers by wrapping the OpenLDAP 2.x libraries, and contains modules for other LDAP-related tasks (including processing LDIF, LDAPURLs, LDAPv3 schema, etc.). Security Fix(es): 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) An update for python-ldap is now available for openEuler-20.03-LTS-SP1 and openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of medium.
