| CVE-2017-17740 | 4 Mcafee, Openldap, Opensuse and 1 more | 4 Policy Auditor, Openldap, Leap and 1 more | 2022-06-13 | 5.0 MEDIUM | 7.5 HIGH |
| contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation. | |||||
| CVE-2019-13565 | 7 Apple, Canonical, Debian and 4 more | 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more | 2022-06-13 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
