'389 directory server'
It was found that the fix for CVE-2018-14648 in 389-ds-base, versions 1.4.0.x before 220.127.116.11, was incorrectly applied in RHEL 7.5. An attacker would still be able to provoke excessive CPU consumption leading to a denial of service.
In 389-ds-base up to version 18.104.22.168, requests are handled by workers threads. Each sockets will be waited by the worker for at most 'ioblocktimeout' seconds. However this timeout applies only for un-encrypted requests. Connections using SSL/TLS are not taking this timeout into account during reads, and may hang longer.An unauthenticated attacker could repeatedly create hanging LDAP requests to hang all the workers, resulting in a Denial of Service.
A flaw was found in 389 Directory Server. A specially crafted search query could lead to excessive CPU consumption in the do_search() function. An unauthenticated attacker could use this flaw to provoke a denial of service.
A flaw was found in 389-ds-base before version 22.214.171.124-13. The process ns-slapd crashes in delete_passwdPolicy function when persistent search connections are terminated unexpectedly leading to remote denial of service.
A vulnerability was discovered in 389-ds-base through versions 126.96.36.199, 188.8.131.52 and 184.108.40.206. The lock controlling the error log was not correctly used when re-opening the log file in log__error_emergency(). An attacker could send a flood of modifications to a very large DN, which would cause slapd to crash.
389-ds-base before versions 220.127.116.11, 18.104.22.168 is vulnerable to a Cleartext Storage of Sensitive Information. By default, when the Replica and/or retroChangeLog plugins are enabled, 389-ds-base stores passwords in plaintext format in their respective changelog files. An attacker with sufficiently high privileges, such as root or Directory Manager, can query these files in order to retrieve plaintext passwords.
389-ds-base before versions 22.214.171.124 and 126.96.36.199 is vulnerable to an invalid pointer dereference in the way LDAP bind requests are handled. A remote unauthenticated attacker could use this flaw to make ns-slapd crash via a specially crafted LDAP bind request, resulting in denial of service.
389-ds-base before versions 188.8.131.52, 184.108.40.206 is vulnerable to a race condition in the way 389-ds-base handles persistent search, resulting in a crash if the server is under load. An anonymous attacker could use this flaw to trigger a denial of service.
389-ds-base before versions 220.127.116.11, 18.104.22.168, 22.214.171.124 did not properly handle long search filters with characters needing escapes, possibly leading to buffer overflows. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.
389 Directory Server 126.96.36.199, when built with mozldap, allows remote attackers to cause a denial of service (replica crash) by sending an empty modify request.
