Description Preview

The vulnerability in RedisBloom, a module used in Redis to add probabilistic data structures, arises from an integer overflow in the CMS.INITBYDIM command. This vulnerability enables an attacker, who has knowledge of the Redis password, to allocate insufficient memory in the heap due to wraparound. Subsequently, the attacker can perform read and write operations beyond the allocated memory, leading to information leakage and out-of-bounds writes. The CMS.INITBYDIM command initializes a Count-Min Sketch with user-specified dimensions, allocating memory based on width and depth values. The issue is resolved in versions 2.2.19, 2.4.12, 2.6.14, and 2.8.2 of RedisBloom.

Overview

The vulnerability (CVE-2024-55656) in RedisBloom allows for remote code execution due to an integer overflow issue in the CMS.INITBYDIM command. It has a CVSS v3.1 base score of 8.8, indicating a high severity level. The attack complexity is low, requiring low privileges, and the impact on confidentiality, integrity, and availability is high. The vulnerability affects RedisBloom versions >= 2.2.0 and < 2.2.19, >= 2.4.0 and < 2.4.12, >= 2.6.0 and < 2.6.14, and >= 2.8.0 and < 2.8.2.

Remediation

To remediate the vulnerability, users of RedisBloom are advised to update their installations to versions 2.2.19, 2.4.12, 2.6.14, or 2.8.2, where the integer overflow issue has been fixed. It is crucial to apply the necessary patches or upgrades promptly to mitigate the risk of remote code execution and potential memory corruption.
