+# Multiple soundness issues

+
+n2 contains multiple soundness issues:
+
+1. Invalid Input Handling in Scanner::slice Method. When using the Scanner::slice method, passing an out-of-bounds argument causes the program to panic abort. This indicates a potential design flaw, as it fails to handle invalid input properly, impacting the stability of the application. [Issue #121](https://github.com/evmar/n2/issues/121)
+2. Out of Bounds Access in Scanner::peek Method. The peek method in the Scanner struct does not handle out-of-bounds accesses correctly. When the internal offset exceeds the length of the buffer, it causes a panic abort. [Issue #122](https://github.com/evmar/n2/issues/122)
+3. Invalid Input Handling in Scanner::peek_newline Method. The peek_newline method fails to handle cases where the internal offset exceeds the size of the buffer, leading to a panic abort. This indicates a design flaw as invalid input is not handled properly. [Issue #123](https://github.com/evmar/n2/issues/123)
