Description

slapo-pcache (overlays/pcache.c) in slapd in OpenLDAP before 2.3.39, when running as a proxy-caching server, allocates memory using a malloc variant instead of calloc, which prevents an array from being initialized properly and might allow attackers to cause a denial of service (segmentation fault) via unknown vectors that prevent the array from being null terminated.

Affected products

openldap: 1.0, 1.0.1, 1.0.2, 1.0.3, 1.1, 1.1.0 (+113)
