The version of openldap installed on the remote host is prior to 2.4.44-25. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2033 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)

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.

For Debian 9 stretch, these problems have been fixed in version 2.4.44+dfsg-5+deb9u7.

We recommend that you upgrade your openldap packages.

  - 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)

  - 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 OpenLDAP before 2.4.57 leading     to a double free and slapd crash in the saslAuthzTo     processing, resulting in denial of     service.(CVE-2020-36225)

  - A flaw was discovered in OpenLDAP before 2.4.57 leading     to a memch->bv_len miscalculation and slapd crash in     the saslAuthzTo processing, resulting in denial of     service.(CVE-2020-36226)

  - A flaw was discovered in OpenLDAP before 2.4.57 leading     to a slapd crash in the Values Return Filter control     handling, resulting in denial of service (double free     and out-of-bounds read).(CVE-2020-36223)

  - A flaw was discovered in OpenLDAP before 2.4.57 leading     to an assertion failure in slapd in the saslAuthzTo     validation, resulting in denial of     service.(CVE-2020-36222)

  - A flaw was discovered in OpenLDAP before 2.4.57 leading     to an invalid pointer free and slapd crash in the     saslAuthzTo processing, resulting in denial of     service.(CVE-2020-36224)

  - An integer underflow was discovered in OpenLDAP before     2.4.57 leading to slapd crashes in the Certificate     Exact Assertion processing, resulting in denial of     service (schema_init.c     serialNumberAndIssuerCheck).(CVE-2020-36221)

  - 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     to an infinite loop in slapd with the cancel_extop     Cancel operation, resulting in denial of     service.(CVE-2020-36227)

  - An integer underflow was discovered in OpenLDAP before     2.4.57 leading to a slapd crash in the Certificate List     Exact Assertion processing, resulting in denial of     service.(CVE-2020-36228)
