CVE-2015-1545
The deref_parseCtrl function in servers/slapd/overlays/deref.c in OpenLDAP 2.4.13 through 2.4.40 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an empty attribute list in a deref control in a search request.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 11.1%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
