CVE-2026-15041 (opens in a new tab)How to fix?
There is no fixed version for 389ds/389-ds-base.
Overview
Affected versions of this package are vulnerable to Timing Attack in the PBKDF2-SHA256 password verification process due to the use of standard memcmp instead of a constant-time comparison. An attacker can infer partial hash information by measuring the time taken for LDAP bind attempts. This is only exploitable if the attacker can perform a large number of authentication attempts and accurately measure response times.
Workaround
This vulnerability can be mitigated by configuring the server to use an alternative password storage scheme (such as SSHA512 or GOST-Yescrypt) that employs constant-time comparison.
