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 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
Two security issues were identified in Redis: an unauthenticated denial of service vulnerability (CVE-2025-48367) and a Hyperloglog out-of-bounds write vulnerability (CVE-2025-32023). Both vulnerabilities affect Redis versions before 7.0.12 as packaged by Red Hat for Red Hat Enterprise Linux 9 and its Extended Update Support releases. The denial of service vulnerability allows unauthenticated attackers to disrupt Redis service availability. The out-of-bounds write vulnerability could lead to memory corruption. Red Hat has issued security advisories and released patched Redis packages (version 7.0.12 and later) to address these issues. The vendor rates the security impact as Important (high). No known exploits in the wild have been reported at this time.
Potential Impact
Successful exploitation of CVE-2025-48367 can cause denial of service without authentication, impacting availability of Redis services. CVE-2025-32023 may allow memory corruption via an out-of-bounds write in the Hyperloglog feature, potentially leading to application instability or crashes. Both vulnerabilities affect Redis deployments on Red Hat Enterprise Linux 9 and related Extended Update Support versions prior to 7.0.12. No reports of active exploitation are known.
Mitigation Recommendations
Red Hat has released fixed Redis packages at version 7.0.12 for Red Hat Enterprise Linux 9 and Extended Update Support releases. Users should apply these official updates promptly to remediate the vulnerabilities. Detailed update instructions are available from Red Hat's advisory and knowledge base articles. No alternative mitigations or workarounds are indicated. Patch status is confirmed as available and official.
