389-ds-base: 389-ds-base: CVE-2026-11610 incomplete fix may introduce a connection-stall DoS

A flaw was found in 389-ds-base. A remote, authenticated attacker could exploit a vulnerability in the Simple Authentication and Security Layer SASL UNBIND process. By sending a specially crafted request, the attacker can cause a connection to stall, leading to resource exhaustion and a Denial of...

389-ds-base: 389-ds-base: heap buffer overflow via SASL wrapped-record length lower-bound underflow in sasl_io_start_packet()

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, the wrapped-record length read from the wire is validated only against an upper bound. A small wire length 0, 1, or 2 produces an encryptedbuffercount below the already-consumed...

389-ds-base: 389-ds: anonymous LDAP client can defeat SELFDN ACI bind-rule checks via empty bind DN

A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated...

389-ds-base: 389-ds-base: SASL PLAIN authentication allows privilege escalation to Directory Manager via stale identity in Cyrus SASL auxiliary property

A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes...
