| Summary | 0008044: parse_fixed_data: integer overflow | ||||
| Description | This is in gnunet/src/lib/json/json_helper.c. 52 static enum GNUNET_GenericReturnValue 53 parse_fixed_data (void *cls, 54 json_t *root, 55 struct GNUNET_JSON_Specification *spec) 56 { 57 const char *enc; 58 unsigned int len; 59 60 if (NULL == (enc = json_string_value (root))) 61 { 62 GNUNET_break_op (0); 63 return GNUNET_SYSERR; 64 } 65 len = strlen (enc); 66 if (((len * 5) / 8) != spec->ptr_size) 67 { len should be a size_t instead of an int, and the * 5 can overflow even after turning len into a size_t. | ||||
