CVE-2017-14159
Public on
Last Modified:
Description
The CVE Program describes this issue as:
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.
Statement
As per upstream this bug can be used only when additional major flaws are found in the slapd binary like the ones caused by heap-based buffer overflows etc. Based on this argument, Red Hat Product Security does not consider this to be a security flaw.

Common Vulnerability Scoring System (CVSS) Score Details
Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
Red Hat | NVD | |
---|---|---|
CVSS v3 Base Score | 4.4 | 4.7 |
Attack Vector | Local | Local |
Attack Complexity | High | High |
Privileges Required | Low | Low |
User Interaction | Required | None |
Scope | Unchanged | Unchanged |
Confidentiality Impact | None | None |
Integrity Impact | None | None |
Availability Impact | High | High |
