Red Hat Security Advisory: redis:7 security update
Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log. Security Fix(es): * redis: Redis Stack Buffer Overflow (CVE-2025-27151) * redis: Redis Unauthenticated Denial of Service (CVE-2025-48367) * redis: Redis Hyperloglog Out-of-Bounds Write Vulnerability (CVE-2025-32023) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
This advisory covers three security vulnerabilities in Redis 7 as packaged by Red Hat for Red Hat Enterprise Linux 9. The vulnerabilities include a stack buffer overflow (CVE-2025-27151), an unauthenticated denial of service (CVE-2025-48367), and a Hyperloglog out-of-bounds write (CVE-2025-32023). These flaws could potentially allow attackers to cause crashes or memory corruption. Red Hat has released a patched version 7.2.10 that addresses these issues. The advisory references Red Hat's security update RHSA-2025:12008 and provides affected package details and update instructions.
Potential Impact
The vulnerabilities could lead to denial of service conditions or memory corruption in Redis servers running affected versions. The stack buffer overflow and out-of-bounds write vulnerabilities may allow an attacker to crash the Redis service or potentially execute arbitrary code, while the unauthenticated denial of service vulnerability allows disruption without authentication. No known exploits in the wild have been reported at this time. The impact is rated as high by Red Hat Product Security.
Mitigation Recommendations
A security update is available and users should upgrade Redis to version 7.2.10 or later as provided by Red Hat Enterprise Linux 9 updates. Refer to Red Hat advisory RHSA-2025:12008 and the article https://access.redhat.com/articles/11258 for detailed update instructions. Applying this official patch fully mitigates the described vulnerabilities.
