Title: Gentoo net-im/jabberd2 privilege escalation via PID file manipulation
Author: Michael Orlitzky
Fixedin: commit b50a3068

Summary

The Gentoo net-im/jabberd2 package gives ownership of its PID file directory to the daemon's runtime user. That can be exploited by the runtime user to kill root processes, since when the service is stopped, root will send a SIGTERM to the contents of the PID file (which are controlled by the runtime user).

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.
