{"id":"DEBIAN-CVE-2026-0994","details":"A denial-of-service (DoS) vulnerability exists in google.protobuf.json_format.ParseDict() in Python, where the max_recursion_depth limit can be bypassed when parsing nested google.protobuf.Any messages.  Due to missing recursion depth accounting inside the internal Any-handling logic, an attacker can supply deeply nested Any structures that bypass the intended recursion limit, eventually exhausting Python’s recursion stack and causing a RecursionError.","modified":"2026-09-02T08:47:35.510749978Z","published":"2026-01-23T15:16:06.840Z","upstream":["CVE-2026-0994"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-0994"}],"affected":[{"package":{"name":"protobuf","ecosystem":"Debian:12","purl":"pkg:deb/debian/protobuf?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.21.12-3+deb12u1"}]}],"versions":["3.21.12-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-0994.json"}},{"package":{"name":"protobuf","ecosystem":"Debian:13","purl":"pkg:deb/debian/protobuf?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.21.12-11+deb13u1"}]}],"versions":["3.21.12-11"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-0994.json"}},{"package":{"name":"protobuf","ecosystem":"Debian:14","purl":"pkg:deb/debian/protobuf?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.21.12-16"}]}],"versions":["3.21.12-11","3.21.12-12","3.21.12-13","3.21.12-14","3.21.12-15"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-0994.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
