Formally speaking, infinity is the identity element of the elliptic curve group and as such it is a member of the group, so the group-check should be performed. The fix performs the check even in the presence of infinity.","affected":[{"package":{"name":"github.com/supranational/blst","ecosystem":"Go"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.3.0"},{"fixed":"0.3.11"}]}],"ecosystem_specific":{"imports":[{"path":"github.com/supranational/blst/bindings/go"}]}}],"references":[{"type":"FIX","url":"https://github.com/supranational/blst/commit/fb91221c91c82f65bfc7f243256308977a06d48b"},{"type":"WEB","url":"https://github.com/supranational/blst/releases/tag/v0.3.11"}],"credits":[{"name":"Yunjong Jeong (@blukat29)"}],"database_specific":{"url":"https://pkg.go.dev/vuln/GO-2023-2003","review_status":"REVIEWED"}}
