Name of the Vulnerable Software and Affected Versions ClickHouse versions prior to 19.14

Description The issue concerns an out-of-bounds (OOB) read, OOB write, and integer underflow in decompression algorithms. This can be exploited to achieve remote code execution (RCE) or cause a denial of service (DoS) via the native protocol.

Recommendations For versions prior to 19.14, update to version 19.14 or later to resolve the issue. As a temporary workaround, consider restricting access to the native protocol to minimize the risk of exploitation.
