CVE-2022-44010​

A heap buffer overflow issue was discovered in ClickHouse server. An attacker could send a specially crafted HTTP request to the HTTP Endpoint (listening on port 8123 by default), causing a heap-based buffer overflow that crashes the ClickHouse server process. This attack does not require authentication.

Fix has been pushed to version 22.9.1.2603, 22.8.2.11, 22.7.4.16, 22.6.6.16, 22.3.12.19

Fixed in ClickHouse 21.10.2.15, 2021-10-18​****CVE-2021-43304​

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.

CVE-2021-43305​

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 very similar to CVE-2021-43304, but the vulnerable copy operation is in a different wildCopy call.

CVE-2021-42387​

Heap out-of-bounds read in ClickHouse’s LZ4 compression codec when parsing a malicious query. As part of the LZ4::decompressImpl() loop, a 16-bit unsigned user-supplied value (‘offset’) is read from the compressed data. The offset is later used in the length of a copy operation, without checking the upper bounds of the source of the copy operation.

CVE-2021-42388​

Heap out-of-bounds read in ClickHouse’s LZ4 compression codec when parsing a malicious query. As part of the LZ4::decompressImpl() loop, a 16-bit unsigned user-supplied value (‘offset’) is read from the compressed data. The offset is later used in the length of a copy operation, without checking the lower bounds of the source of the copy operation.

CVE-2021-42389​

Divide-by-zero in ClickHouse’s Delta 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.

CVE-2021-42390​

Divide-by-zero in ClickHouse’s DeltaDouble 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.

Fixed in ClickHouse Release 19.14.3.3, 2019-09-10​****CVE-2019-15024​

Аn attacker that has write access to ZooKeeper and who can run a custom server available from the network where ClickHouse runs, can create a custom-built malicious server that will act as a ClickHouse replica and register it in ZooKeeper. When another replica will fetch data part from the malicious replica, it can force clickhouse-server to write to arbitrary path on filesystem.
