An authenticated user (with the ability to An issue was discovered in ClickHouse before 22.9.1.2603. An authenticated user (with the ability to load data) could cause a heap buffer overflow and crash the server by inserting a malformed CapnProto object. The fixed versions are 22.9.1.2603, 22.8.2.11, 22.7.4.16, 22.6.6.16, and 22.3.12.19.

CVE-2021-43304 [HIGH] CWE-122 CVE-2021-43304: Heap buffer overflow in Clickhouse's LZ4 compression codec when parsing a malicious query. There is 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(op, ip, copy_end), don’t exceed the destination buffer’s limits.

CVE-2021-42388 [HIGH] CWE-125 CVE-2021-42388: Heap out-of-bounds read in Clickhouse's LZ4 compression codec when parsing a malicious query. As par 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.
