Description of vulnerabilities ========================== These two vulnerabilities were tested only against the MikroTik RouterOS stable release tree when found. Maybe other release trees also suffer from these vulnerabilities. 1. The cerm process suffers from an uncontrolled resource consumption issue. By sending a crafted packet, an authenticated remote user can cause a high cpu load, which may make the device respond slowly or unable to respond. 2. The traceroute process suffers from a memory corruption issue. By sending a crafted packet, an authenticated remote user can crash the traceroute process due to invalid memory access. Solution ======== Upgrade to the corresponding latest RouterOS tree version. References ========== [1] https://mikrotik.com/download/changelogs/stable-release-tree
