Openswan 2.2.x does not properly restrict permissions for (1) /var/run/starter.pid, related to starter.c in the IPsec starter, and (2) /var/lock/subsys/ipsec, which allows local users to kill arbitrary processes by writing a PID to a file, or possibly bypass disk quotas by writing arbitrary data to a file, as demonstrated by files with 0666 permissions, a different vulnerability than CVE-2011-1784.

Security readout for executives and security teams

This is a legacy Openswan issue where local users could abuse overly permissive PID and lock files. In business terms, the main concern is service disruption on affected VPN/IPsec hosts, not internet-scale remote compromise based on the provided sources. Exposure is likely limited to legacy systems running Openswan 2.2.x with local untrusted user access. The source bundle does not identify affected CPEs, platforms, or maintained package versions. Treat as a targeted legacy hardening issue. Prioritize if affected VPN/IPsec servers permit local multi-user access or support critical connectivity. Otherwise, track through normal vulnerability management. Mitigation focus: Check vendor or distribution advisories for the supported Openswan fix or replacement guidance.; Remove or upgrade legacy Openswan 2.2.x installations where possible.; Verify affected PID and lock files are not world-writable..
