NIST CVE Summary
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 Severity
Our Official Summary
This is a high-severity vulnerability in OpenLDAP versions up to 2.4.45. It arises when both the nops module and the memberof overlay are enabled. In this configuration, the nops module attempts to free a buffer that was allocated on the stack, leading to a stack-based buffer overflow. This flaw allows remote attackers to cause a denial of service (DoS) by crashing the slapd daemon through a crafted MODDN (Modify Distinguished Name) operation.
Risk of exploitation is low for our products as attacker has to gain privilged access to the container and run code on the container to be able to exploit this. Probability of exploitation is very low. If a fix becomes available upstream, that will be adopted to fix this vulnerability.
