Vulnerability identifier: #VU37389

Vulnerability risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CWE-ID: CWE-20

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
collectd
Server applications / DLP, anti-spam, sniffers

Vendor: collectd

Description

The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.

The Gentoo app-admin/collectd package before 5.7.2-r1 sets the ownership of PID file directory to the collectd account, which might allow local users to kill arbitrary processes by leveraging access to this account for PID file modification before a root script sends a SIGKILL (when the service is stopped).

Mitigation
Install update from vendor's website.

Vulnerable software versions

collectd: 5.7.2
