MediumCVE-2021-42389clickhouse +1 moreclickhouse clickhouseDivide-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.EPSS1.26%MediumCVE-2021-42390clickhouse +1 moreclickhouse clickhouseDivide-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.EPSS1.26%HighCVE-2021-42388clickhouse +4 moreclickhouse clickhouseHeap 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.EPSS1.57%MediumCVE-2021-42391clickhouse +1 moreclickhouse clickhouseDivide-by-zero in Clickhouse's Gorilla 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.EPSS1.67%HighCVE-2021-43305clickhouse +4 moreclickhouse clickhouseHeap 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.EPSS1.67%
