Redis · Redis · CVE-2018-12326
**Name of the Vulnerable Software and Affected Versions**
Redis versions prior to 4.0.10
Redis versions 5.x prior to 5.0 RC3
**Description**
The issue is related to a buffer overflow in the redis-cli interface of the Redis database management system. This buffer overflow is due to improper restriction of operations within a memory buffer. An attacker can exploit this issue by using a crafted command line, potentially leading to code execution, privilege escalation, and access to confidential data. The exploitation could also disrupt data integrity and cause a denial of service.
**Recommendations**
For Redis versions prior to 4.0.10, update to version 4.0.10 or later.
For Redis versions 5.x prior to 5.0 RC3, update to version 5.0 RC3 or later.
As a temporary workaround, consider restricting the use of the redis-cli interface until a patch is applied. Avoid using the redis-cli with untrusted input, especially with arguments like hostname (-h) that could be manipulated by an attacker.
