UBUNTU-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...

Heap overflow

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 wildCopyop, ip, copyend, don’t exceed the destination buffer’s limits...

CVE-2021-42387

CVE-2021-42387 affects ClickHouse. It describes a heap out-of-bounds read in the LZ4 compression codec during parsing a malicious query: a 16-bit unsigned offset read in LZ4::decompressImpl() is used to determine the copy length without checking the upper bounds of the source, potentially causing...

CVE-2021-43305

Summary : CVEs 2021-43304 and 2021-43305 describe heap/ buffer issues in ClickHouse’s LZ4 compression codec during parsing of crafted queries, due to unsafe copy bounds in LZ4::decompressImpl and the wildCopy function. The connected documents confirm a related set of advisories and mitigations ac...

CVE-2021-43304

CVE-2021-43304 describes a heap-buffer overflow in ClickHouse’s LZ4 compression codec when parsing a malicious query. The root cause is the LZ4::decompressImpl loop, where the arbitrary copy operation wildCopy(op, ip, copy_end) can exceed the destination buffer’s bounds. This vulnerability is lin...

CVE-2021-42388

CVE-2021-42388 affects ClickHouse’s LZ4 compression codec. In LZ4::decompressImpl(), a 16-bit unsigned offset is read from the compressed data and later used to determine a copy length without lower-bound source checks, causing a heap out-of-bounds read. This could enable crashes or memory-access...
