    Package        : 389-ds-base     Version        : 1.4.4.11-2+deb11u1     CVE ID         : CVE-2021-3652 CVE-2021-4091 CVE-2022-0918 CVE-2022-0996                      CVE-2022-2850 CVE-2024-2199 CVE-2024-3657 CVE-2024-5953                      CVE-2024-8445

    This update fixes multiple vulnerabilities in 389-ds-base LDAP server.

    CVE-2021-3652

        If an asterisk is imported as password hashes, either accidentally         or maliciously, then instead of being inactive, any password will         successfully match during authentication. This flaw allows an attacker         to successfully authenticate as a user whose password was disabled.

    CVE-2021-4091

        A double-free was found in the way 389-ds-base handles virtual         attributes context in persistent searches. An attacker could send a         series of search requests, forcing the server to behave unexpectedly,         and crash.

    CVE-2022-0918

        A vulnerability allows an unauthenticated attacker with network         access to the LDAP port to cause a denial of service. The denial of         service is triggered by a single message sent over a TCP connection,         no bind or other authentication is required. The message triggers         a segmentation fault that results in slapd crashing.

    CVE-2022-0996

        A vulnerability allows expired passwords to access the database to         cause improper authentication.

    CVE-2022-2850

        When the content synchronization plugin is enabled, an authenticated         user can reach a NULL pointer dereference using a specially         crafted query. This flaw allows an authenticated attacker to cause         a denial of service. This CVE is assigned against an incomplete fix         of CVE-2021-3514.

    CVE-2024-2199

        A denial of service vulnerability that may allow an authenticated         user to cause a server crash while modifying `userPassword` using         malformed input.

    CVE-2024-3657

        A specially-crafted LDAP query can potentially cause a failure on         the directory server, leading to a denial of service.

    CVE-2024-5953

        This issue may allow an authenticated user to cause a server denial         of service while attempting to log in with a user with a malformed         hash in their password.

    CVE-2024-8445

        The fix for CVE-2024-2199 in 389-ds-base was insufficient to cover         all scenarios. In certain product versions, an authenticated user         may cause a server crash while modifying `userPassword` using         malformed input.

    For Debian 11 bullseye, these problems have been fixed in version     1.4.4.11-2+deb11u1.
