389 Directory Server security vulnerability
389 Directory Server is an open-source implementation of a highly available, fully functional, reliable, and secure LDAP server. There is a security vulnerability in 389 Directory Server, which stems from the fact that the length of the ocsuperior field is not taken into account when calculating...
CVE-2026-11884: Heap-based Buffer Overflow
A heap buffer overflow flaw was found in 389 Directory Server. When serializing objectclass definitions, the ocsuperior SUP field length is omitted from buffer size calculations in readschemadse and schemaoctostring, but the field is still written via strcat. An attacker with Directory Manager...

Name of the Vulnerable Software and Affected Versions 389 Directory Server affected versions not specified Description A flaw exists during schema reload where the attr syntax swap ht function unconditionally frees attribute syntax information nodes. This action bypasses the refcount-based deferr...
CVE-2026-11792
A heap buffer overflow flaw was found in 389 Directory Server. When audit logging is enabled, the createmaskedentrystring 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 requiri...
CVE-2026-11789
A flaw was found in 389 Directory Server. The SMD5 password storage plugin performs unsigned integer underflow when computing salt length from a crafted password hash shorter than 16 bytes, causing a buffer over-read that crashes the LDAP server during authentication...
CVE-2026-11793
A stack buffer overflow flaw was found in 389 Directory Server. The checkPrefix function in pw.c copies an attacker-controlled algorithm ID into a 256-byte stack buffer without bounds checking when parsing reversible-encrypted attribute values. An attacker with Directory Manager privileges can...
DEBIAN-CVE-2026-11790
A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password storage plugin does not enforce an upper bound on the iteration count extracted from stored password hashes. A privileged attacker who can modify a user's password hash can cause excessive CPU consumption during authentication,...
