Updated openldap packages fix security vulnerabilities: When both the nops module and the member of 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-2017-17740). In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can result in denial of service (daemon crash) (CVE-2020-12243). The nops overlay has been dropped from the package, fixing CVE-2017-17740. The openldap package has been updated to version 2.4.50, fixing CVE-2020-12243 and several other bugs.
