CVE-2019-5607: FreeBSD vulnerability

CVE-2019-5607: In FreeBSD 12.0-STABLE before r350222, 12.0-RELEASE before 12.0-RELEASE-p8, 11.3-STABLE before r350223, 11....

In FreeBSD 12.0-STABLE before r350222, 12.0-RELEASE before 12.0-RELEASE-p8, 11.3-STABLE before r350223, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RELEASE-p12, rights transmitted over a domain socket did not properly release a reference on transmission error allowing a malicious user to cause the reference counter to wrap, forcing a free event. This could allow a malicious local user to gain root privileges or escape from a jail.

Security readout for executives and security teams

CVE-2019-5607 is a FreeBSD local privilege escalation issue. A malicious local user could abuse incorrect reference handling in domain socket rights transmission to gain root privileges or escape a jail. The issue matters most on shared FreeBSD systems, jail hosts, and appliances using affected FreeBSD versions. Exposure is likely limited to FreeBSD systems running the listed vulnerable 12.0, 11.3, or 11.2 branches before the named patch levels. Highest concern is systems granting local accounts, hosting untrusted workloads, or relying on FreeBSD jails for isolation. Treat as high priority for FreeBSD systems with local users or jail-based isolation. This is not described as remotely exploitable, but successful exploitation could cross a critical privilege boundary and undermine tenant or workload separation. Mitigation focus: Upgrade FreeBSD to the fixed release or stable revision named by FreeBSD.; Apply 12.0-RELEASE-p8, 11.3-RELEASE-p1, or 11.2-RELEASE-p12 where applicable.; For STABLE branches, verify r350222 or r350223 is included as applicable..
