🔒 Fix: Unvalidated Input in ANSI RGB Parser#7
Conversation
… invalid RGB data The ANSI parser previously relied on `byte.Parse` when processing RGB values for `#fg:`, `#bg:`, and `#` sequences. This resulted in an unhandled `FormatException` or `OverflowException` instead of the expected `ArgumentException` if the inputs were malformed. This change replaces `byte.Parse` with `byte.TryParse` to validate RGB inputs gracefully. Co-authored-by: johnstrand <11484777+johnstrand@users.noreply.github.com>

🎯 What: The vulnerability fixed is an unvalidated input issue in the ANSI parser in
Term/Ansi.csthat attempts to parse RGB strings usingbyte.Parse().FormatExceptionorOverflowExceptionwhich bypasses the intendedArgumentException. This could potentially crash the process or leave it in an unstable state.🛡️ Solution: The solution replaces
byte.Parsewithbyte.TryParseto ensure parsing is performed safely. If validation fails, it throws the appropriate and intendedArgumentExceptionindicating a malformed ANSI sequence without resulting in arbitrary parsing failures.PR created automatically by Jules for task 5631791546694099065 started by @johnstrand
