A flaw was found in RHDS 11 and RHDS 12. While browsing entries LDAP tries to decode the userPassword attribute instead of the userCertificate attribute which could lead into sensitive information leaked. An attacker with a local account where the cockpit-389-ds is running can list the processes and display the hashed passwords. The highest threat from this vulnerability is to data confidentiality.
A flaw was found In 389-ds-base. 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.
An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data.
A vulnerability was discovered in the 389 Directory Server that 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.
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.
A flaw was found in the 'deref' plugin of 389-ds-base where it could use the 'search' permission to display attribute values. In some configurations, this could allow an authenticated attacker to view private attributes, such as password hashes.
In 389-ds-base up to version 1.4.1.2, 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 stack buffer overflow flaw was found in the way 389-ds-base 1.3.6.x before 1.3.6.13, 1.3.7.x before 1.3.7.9, 1.4.x before 1.4.0.5 handled certain LDAP search filters. 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 in Red Hat Enterprise Linux Desktop 6 through 7, Red Hat Enterprise Linux HPC Node 6 through 7, Red Hat Enterprise Linux Server 6 through 7, and Red Hat Enterprise Linux Workstation 6 through 7 allows remote attackers to infer the existence of RDN component objects.
