A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE).

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:5196 advisory.

    389 Directory Server is an LDAP version 3 (LDAPv3) compliant server. The base packages include the     Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.

    Security Fix(es):

    * 389-ds-base: 389-ds-base: Remote Code Execution and Denial of Service via heap buffer overflow     (CVE-2025-14905)
