Vulnerability from github – Published: 2026-06-08 18:31 – Updated: 2026-06-08 18:31

Details

A flaw was found in 389 Directory Server. The Content Synchronization persistent search plugin allows unbounded memory growth when an authenticated client stops reading sync responses, enabling denial of service. Additional race conditions in plugin thread lifecycle can cause crashes during connection teardown or shutdown.

Severity

6.5 (Medium)
