CVE-2020-14976
GNS3 ubridge through 0.9.18 on macOS, as used in GNS3 server before 2.1.17, allows a local attacker to read arbitrary files because it handles configuration-file errors by printing the configuration file while executing in a setuid root context.
Does this matter?
Lower severity and a low EPSS score (0.48%). Track it; it rarely justifies an emergency change on its own.
