CVE-2025-14905 – 389-ds-base: 389-ds-base: remote code execution and denial of service via heap buffer overflow

CVE ID : CVE-2025-14905

Published : Feb. 23, 2026, 4:29 p.m. | 36 minutes ago

Description : 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).

Severity: 7.2 | HIGH
