| Summary | 0009328: add_record: buffer overflow | ||||
| Description | 1297 ret = GNUNET_DNSPARSER_builder_add_name (dst, 1298 dst_len 1299 - sizeof( 1300 struct GNUNET_TUN_DnsRecordLine), 1301 off, 1302 record->name); dst_len could come in < sizeof(struct GNUNET_TUN_DnsRecordLine) and cause underflow and a buffer overflow here. 1343 default: 1344 if (pos + record->data.raw.data_len > dst_len) data_len is a size_t. This addition can overflow, defeating the check. | ||||
