NVD Description

Note: Versions mentioned in the description apply only to the upstream 389-ds-base-legacy-tools package and not the 389-ds-base-legacy-tools package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

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 crash the LDAP server by storing a crafted credential with an oversized algorithm ID. FORTIFY_SOURCE mitigates this to denial of service only.
