------------------------------------------------------------------------- Debian LTS Advisory DLA-3176-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Tobias Frost November 03, 2022 https://wiki.debian.org/LTS

Package : clickhouse Version : 18.16.1+ds-4+deb10u1 CVE ID : CVE-2021-42387 CVE-2021-42388 CVE-2021-43304 CVE-2021-43305 Debian Bug : 1008216

Several security vulnerabilities were discovered in clickhouse, a column-oriented database system.

The vulnerabilities require authentication, but can be triggered by any user with read permissions. This means the attacker must perform reconnaissance on the specific ClickHouse server target to obtain valid credentials. Any set of credentials would do, since even a user with the lowest privileges can trigger all of the vulnerabilities. By triggering the vulnerabilities, an attacker can crash the ClickHouse server, leak memory contents or even cause remote code execution.

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-2021-43304:
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.

For Debian 10 buster, these problems have been fixed in version 18.16.1+ds-4+deb10u1.

We recommend that you upgrade your clickhouse packages.
