RedisBloom Integer Overflow Remote Code Execution Vulnerability

RedisBloom adds a set of probabilistic data structures to Redis. There is an integer overflow vulnerability in RedisBloom, which is a module used in Redis. The integer overflow vulnerability allows an attacker (a redis client which knows the password) to allocate memory in the heap lesser than the required memory due to wraparound. Then read and write can be performed beyond this allocated memory, leading to info leak and OOB write. The integer overflow is in CMS.INITBYDIM command, which initialize a Count-Min Sketch to dimensions specified by user. It accepts two values (width and depth) and uses them to allocate memory in NewCMSketch(). This vulnerability is fixed in 2.2.19, 2.4.12, 2.6.14, and 2.8.2.

整数溢出或超界折返

RedisBloom 输入验证错误漏洞

RedisBloom是RedisBloom开源的一个库。为 Redis 添加了一组概率数据结构。 RedisBloom存在输入验证错误漏洞，该漏洞源于存在整数溢出漏洞，允许攻击者在堆中分配小于所需内存的内存，然后可以超出分配的内存执行读写操作，导致信息泄露和越界写入。
