Possible DoS Exposure in Large int to str Conversions
“A Denial Of Service (DoS) issue was identified in CPython because we use binary bignum’s for our int implementation. A huge integer will always consume a near-quadratic amount of CPU time in conversion to or from a base 10 (decimal) string with a large number of digits. No efficient algorithm exists to do otherwise.”
