Synopsis:

389-ds-base security updateSummary:

An update for 389-ds-base is now available for openEuler-20.03-LTS-SP4Description:

389-ds-base is an LDAPv3 compliant server which includes the LDAP server and command line utilities for server administration.

Security Fix(es):

A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), causing excessive CPU consumption and heap allocation on the server. Under concurrent exploitation, this leads to significant latency degradation, worker thread starvation, or out-of-memory termination, resulting in a denial of service.(CVE-2026-9064)Topic:
