CVE-2017-14159 (CCN-131540)

Assigned:2017-09-05
Published:2017-09-05
Updated:2022-06-13
Summary:slapd in OpenLDAP 2.4.45 and earlier creates a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill `cat /pathname`" command, as demonstrated by openldap-initscript.
