This does not require authentication. The fixed versions are 22.9.1.2603, 22.8.2.11, 22 | 23/11/2023 |
| CVE-2021-43305 | ALTO8.8 | Heap buffer overflow in Clickhouse's LZ4 compression codec when parsing a malicious query. There is no verification that the copy operations in the LZ4::decompressImpl loop and especially the arbitrary copy operation wildCopy<copy_amount>(op, ip, copy_end), don’t exceed the destination buffer’s limits. This issue is ve | 14/03/2022 |
| CVE-2021-43304 | ALTO8.8 | Heap buffer overflow in Clickhouse's LZ4 compression codec when parsing a malicious query. There is no verification that the copy operations in the LZ4::decompressImpl loop and especially the arbitrary copy operation wildCopy<copy_amount>(op, ip, copy_end), don’t exceed the destination buffer’s limits. | 14/03/2022 |
| CVE-2021-42391 | MEDIO6.5 | Divide-by-zero in Clickhouse's Gorilla compression codec when parsing a malicious query. The first byte of the compressed buffer is used in a modulo operation without being checked for 0. | 14/03/2022 |
