Hi,

The following vulnerability was published for 389-ds-base.

CVE-2025-14905[0]:
| 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).


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
