CVE-2017-14159 (GCVE-0-2017-14159)

Vulnerability from cvelistv5 – Published: 2017-09-05 18:00 – Updated: 2024-08-05 19:20

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.

Severity

No CVSS data available.
