CVE ID | Published | Description | Score | Severity |
---|---|---|---|---|
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. | 6.5 |
Medium |
||
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. | 6.5 |

Medium |
||
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. | 8.1 |

In all versions of ClickHouse before 19.14.3, an attacker having write access to ZooKeeper and who is able to 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. | 6.5 |
Medium |
||
In all versions of ClickHouse before 19.14, an OOB read, OOB write and integer underflow in decompression algorithms can be used to achieve RCE or DoS via native protocol. | 9.8 |
Critical |
||
ClickHouse before 19.13.5.44 allows HTTP header injection via the url table function. | 5.3 |
Medium |
||
In ClickHouse before 18.12.13, functions for loading CatBoost models allowed path traversal and reading arbitrary files through error messages. | 5.3 |
Medium |
||
In ClickHouse before 18.10.3, unixODBC allowed loading arbitrary shared objects from the file system which led to a Remote Code Execution vulnerability. | 9.8 |
