Several vulnerabilities were discovered in OpenLDAP, a free implementation of the Lightweight Directory Access Protocol. An unauthenticated remote attacker can take advantage of these flaws to cause a denial of service (slapd daemon crash, infinite loops) via specially crafted packets.

According to the versions of the openldap packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - In OpenLDAP through 2.4.57 and 2.5.x through     2.5.1alpha, an assertion failure in slapd can occur in     the issuerAndThisUpdateCheck function via a crafted     packet, resulting in a denial of service (daemon exit)     via a short timestamp. This is related to schema_init.c     and checkTime.(CVE-2021-27212)

  - A flaw was discovered in OpenLDAP before 2.4.57 leading     in an assertion failure in slapd in the X.509 DN     parsing in decode.c ber_next_element, resulting in     denial of service.(CVE-2020-36230)

  - A flaw was discovered in ldap_X509dn2bv in OpenLDAP     before 2.4.57 leading to a slapd crash in the X.509 DN     parsing in ad_keystring, resulting in denial of     service.(CVE-2020-36229)

The version of openldap installed on the remote host is prior to 2.4.40-16.36. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1741 advisory.

    An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session     encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain     access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the     first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending     on the ACL configuration, this can affect different types of operations (searches, modifications, etc.).
    In other words, a successful authorization step completed by one user affects the authorization     requirement for a different user. (CVE-2019-13565)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.4 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

 - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30712)

  - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30678)

  - An application may be able to execute arbitrary code with kernel privileges. (CVE-2021-30704)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

A flaw was discovered in OpenLDAP before 2.4.57 leading to a double free and slapd crash in the saslAuthzTo processing, resulting in denial of service.
