| CVE-2022-29155 | Cri | 0.69 | 9.8 | 0.64 | May 4, 2022 | In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2, a SQL injection vulnerability exists in the experimental back-sql backend to slapd, via a SQL statement within an LDAP query. This can occur during an LDAP search operation when the search filter is processed, due to a lack… | ||
| CVE-2010-0211 | Cri | 0.69 | 9.8 | 0.28 | Jul 28, 2010 | The slap_modrdn2mods function in modrdn.c in OpenLDAP 2.4.22 does not check the return value of a call to the smr_normalize function, which allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a modrdn call with an RDN… | ||
| CVE-2006-5779 | Hig | 0.55 | 7.5 | 0.76 | Nov 7, 2006 | OpenLDAP before 2.3.29 allows remote attackers to cause a denial of service (daemon crash) via LDAP BIND requests with long authcid names, which triggers an assertion failure. | ||
| CVE-2021-27212 | Hig | 0.54 | 7.5 | 0.64 | Feb 14, 2021 | 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-2023-2953 | Hig | 0.49 | 7.5 | 0.02 | May 30, 2023 | A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function. | ||

This flaw allows an attacker who sends a malicious packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this vulnerability is to system availability. | ||
| CVE-2020-25709 | Hig | 0.49 | 7.5 | 0.03 | May 18, 2021 | A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed by OpenLDAP’s slapd server, to trigger an assertion failure. The highest threat from this vulnerability is to system availability. | ||
| CVE-2020-25692 | Hig | 0.49 | 7.5 | 0.02 | Dec 8, 2020 | A NULL pointer dereference was found in OpenLDAP server and was fixed in openldap 2.4.55, during a request for renaming RDNs.
