| 4 | Subject: [PATCH 1/2] headers: Be more robust against invalid input when | ||
| 5 | parsing params | ||
| 6 | |||
| 7 | If you pass invalid input to a function such as soup_header_parse_param_list_strict() | ||
| 8 | it can cause an overflow if it decodes the input to UTF-8. | ||
| 9 | |||
| 10 | This should never happen with valid UTF-8 input which libsoup's client API | ||
| 11 | ensures, however it's server API does not currently. | ||
