UltraJSON has an integer overflow handling large indent leads to buffer overflow or infinite loop

Summary ujson.dumps crashes the Python interpreter segmentation fault when the product of the indent parameter and the nested depth of the input exceeds INT32MAX. It can also get stuck in an infinite loop if the indent is a large negative number. Both are caused by an integer overflow/underflow...

GHSA-9XP9-J92R-P88V Parse Server crash via deeply nested query condition operators

Impact An unauthenticated attacker can crash the Parse Server process by sending a single request with deeply nested query condition operators. This terminates the server and denies service to all connected clients. Patches A depth limit for query condition operator nesting has been added via the...
