CVE-2026-9064

The CVE-2026-9064 issue affects the 389-ds-base LDAP server. The get_ldapmessage_controls_ext() function does not bound the number of LDAP message controls, allowing a remote, unauthenticated attacker to send requests with hundreds of thousands of minimal controls within the default BER size (2 M...

CVE-2026-9064 389-ds-base: 389-ds-base: unbounded ldap controls count in get_ldapmessage_controls_ext() causes cpu and heap amplification (remote dos)

A flaw was found in 389-ds-base. The getldapmessagecontrolsext 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...
