FKIE_CVE-2026-11792

Vulnerability from fkie_nvd - Published: 2026-06-09 14:16 - Updated: 2026-07-23 08:10
Severity
3.3 (Low) - CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:L
Summary
A heap buffer overflow flaw was found in 389 Directory Server. When audit logging is enabled, the create_masked_entry_string() function in auditlog.c copies a fixed-length password mask into a precisely-sized heap buffer without checking available space. If a short cleartext password is logged (requiring non-default CLEAR password storage or a compromised replication peer), the copy overflows the buffer, corrupting heap memory and audit log output.
