An issue was discovered in GOG Galaxy Client 2.0.17. Local escalation of privileges is possible when a user starts or uninstalls a game because of weak file permissions and missing file integrity checks.
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
