Arbitrary file write via symlinked SQLite path

Insecure temporary file handling in Linuxfabrik Monitoring Plugins before 4.2.0 allows local users to write root-owned files via symlinked SQLite paths. In db_sqlite.py, connect() resolves database files at predictable names under shared /tmp, and the vulnerable code opens those paths without rejecting attacker-planted symlinks before sqlite3.connect() creates or updates the target. Exploitation requires control of the monitoring account and a sudo-authorized plugin execution path; affected deployments can suffer arbitrary file overwrite, service interrupt, or modification of an existing SQLite database through crafted journal or WAL files.
