In affected versions an integer overflow bug in Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default proto-max-bulk-len and client-query-buffer-limit configuration parameters to very large values and constructing specially crafted very large stream elements. The problem is fixed in Redis 6.2.6, 6.0.16 and 5.0.14. For users unable to upgrade an additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the proto-max-bulk-len configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "Alpine-Linux-3.23:redis7-7.0.15.tuxcare.els7-r0.aarch64", "Alpine-Linux-3.23:redis7-7.0.15.tuxcare.els7-r0.x86_64", "Alpine-Linux-3.23:redis7-openrc-7.0.15.tuxcare.els7-r0.aarch64", "Alpine-Linux-3.23:redis7-openrc-7.0.15.tuxcare.els7-r0.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2021-32627" }, { "category": "external", "summary": "https://github.com/redis/redis/commit/f6a40570fa63d5afdd596c78083d754081d80ae3", "url": "https://github.com/redis/redis/commit/f6a40570fa63d5afdd596c78083d754081d80ae3" }, { "category": "external", "summary": "https://github.com/redis/redis/security/advisories/GHSA-f434-69fm-g45v", "url": "https://github.com/redis/redis/security/advisories/GHSA-f434-69fm-g45v" }, { "category": "external", "summary": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42/", "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42/" }, { "category": "external", "summary": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z/", "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z/" }, { "category": "external", "summary": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB/", "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB/" }, { "category": "external", "summary": "https://security.gentoo.org/glsa/202209-17", "url": "https://security.gentoo.org/glsa/202209-17" }, { "category": "external", "summary": "https://security.netapp.com/advisory/ntap-20211104-0003/", "url": "https://security.netapp.com/advisory/ntap-20211104-0003/" }, { "category": "external", "summary": "https://www.debian.org/security/2021/dsa-5001", "url": "https://www.debian.org/security/2021/dsa-5001" }, { "category": "external", "summary": "https://www.oracle.com/security-alerts/cpuapr2022.html", "url": "https://www.oracle.com/security-alerts/cpuapr2022.html" } ], "release_date": "2021-10-04T18:15:00Z", "scores": [ { "cvss_v3": { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1" }, "products": [ "Alpine-Linux-3.23:redis7-7.0.15.tuxcare.els7-r0.aarch64", "Alpine-Linux-3.23:redis7-7.0.15.tuxcare.els7-r0.x86_64", "Alpine-Linux-3.23:redis7-openrc-7.0.15.tuxcare.els7-r0.aarch64", "Alpine-Linux-3.23:redis7-openrc-7.0.15.tuxcare.els7-r0.x86_64" ] } ], "threats": [ { "category": "impact", "details": "Important" } ] } ] }
