* [NRBF] Don't use Unsafe.As when decoding DateTime(s) (#105749) * Add NrbfDecoder Fuzzer (#107385) * [NRBF] Fix bugs discovered by the fuzzer (#107368) * bug #1: don't allow for values out of the SerializationRecordType enum range * bug #2: throw SerializationException rather than KeyNotFoundException when the referenced record is missing or it points to a record of different type * bug #3: throw SerializationException rather than FormatException when it's being thrown by BinaryReader (or sth else that we use) * bug #4: document the fact that IOException can be thrown * bug #5: throw SerializationException rather than OverflowException when parsing the decimal fails * bug #6: 0 and 17 are illegal values for PrimitiveType enum * bug #7: throw SerializationException when a surrogate character is read (so far an ArgumentException was thrown) # Conflicts: # src/libraries/System.Formats.Nrbf/src/System/Formats/Nrbf/NrbfDecoder.cs * [NRBF] throw SerializationException when a surrogate character is read (#107532) (so far an ArgumentException was thrown) * [NRBF] Fuzzing non-seekable stream input (#107605) * [NRBF] More bug fixes (#107682) - Don't use `Debug.Fail` not followed by an exception (it may cause problems for apps deployed in Debug) - avoid Int32 overflow - throw for unexpected enum values just in case parsing has not rejected them - validate the number of chars read by BinaryReader.ReadChars - pass serialization record id to ex message - return false rather than throw EndOfStreamException when provided Stream has not enough data - don't restore the position in finally - limit max SZ and MD array length to Array.MaxLength, stop using LinkedList<T> as List<T> will be able to hold all elements now - remove internal enum values that were always illegal, but needed to be handled everywhere - Fix DebuggerDisplay * [NRBF] Comments and bug fixes from internal code review (#107735) * copy comments and asserts from Levis internal code review * apply Levis suggestion: don't store Array.MaxLength as a const, as it may change in the future * add missing and fix some of the existing comments * first bug fix: SerializationRecord.TypeNameMatches should throw ArgumentNullException for null Type argument * second bug fix: SerializationRecord.TypeNameMatches should know the difference between SZArray and single-dimension, non-zero offset arrays (example: int[] and int[*]) * third bug fix: don't cast bytes to booleans * fourth bug fix: don't cast bytes to DateTimes * add one test case that I've forgot in previous PR # Conflicts: # src/libraries/System.Formats.Nrbf/src/System/Formats/Nrbf/SerializationRecord.cs * [NRBF] Address issues discovered by Threat Model (#106629) * introduce ArrayRecord.FlattenedLength * do not include invalid Type or Assembly names in the exception messages, as it's most likely corrupted/tampered/malicious data and could be used as a vector of attack. * It is possible to have binary array records have an element type of array without being marked as jagged --------- Co-authored-by: Buyaa Namnan <bunamnan@microsoft.com>
