Title: OpenLDAP privilege escalation via PID file manipulation
Author: Michael Orlitzky
The slapd daemon in all versions of OpenLDAP creates a PID file after dropping privileges to a non-root account. That may be exploitable by the non-root account to kill root processes, because any root script (for example a SysV-style init script) that tries to stop the daemon using the PID file will send a SIGTERM to its contents. The init script provided by the LDAP Tool Box Project is one example of such an init script.

What is CVE?
Common Vulnerabilities and Exposures (CVE®) is a list of common identifiers for publicly known cybersecurity vulnerabilities, and is the industry standard for vulnerability and exposure identifiers.
The process of creating a CVE Entry begins with the discovery of a potential security vulnerability. The MITRE Corporation currently maintains CVE and this public website, oversees the CNAs and CVE Board, and provides impartial technical guidance throughout the process to ensure CVE serves the public interest.
