Fix CVE(s): CVE-2024-7254, CVE-2026-0994
Type: advisorySources: OSV
* SECURITY UPDATE: Unbounded recursion when parsing nested groups in protobuf-java - debian/patches/CVE-2024-7254.patch: bound the depth of the skipMessage()/skipField() recursion in CodedInputStream and of the nested-group recursion in UnknownFieldSetLite with the existing recursion limit, so a stream of nested SGROUP tags can no longer exhaust the Java stack - CVE-2024-7254 * SECURITY UPDATE: Nested Any messages bypass the JSON parser recursion depth limit in python-protobuf - debian/patches/CVE-2026-0994.patch: add max_recursion_depth accounting to json_format and route nested well-known types in _ConvertAnyMessage() through ConvertMessage() so the depth is tracked - CVE-2026-0994
