An integer overflow bug in Redis version 6.0 or newer, could be exploited using the STRALGO LCS command to corrupt the heap and potentially result with remote code execution. This is a result of an incomplete fix by CVE-2021-29477. The problem is fixed in version 6.2.4 and 6.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to use ACL configuration to prevent clients from using the STRALGO LCS command. On 64 bit systems which have the fixes of CVE-2021-29477 (6.2.3 or 6.0.13), it is sufficient to make sure that the proto-max-bulk-len config parameter is smaller than 2GB (default is 512MB).", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Alpine-Linux-3.24:redis6.2-6.2.21.tuxcare.els7-r0.aarch64", "Alpine-Linux-3.24:redis6.2-6.2.21.tuxcare.els7-r0.x86_64", "Alpine-Linux-3.24:redis6.2-openrc-6.2.21.tuxcare.els7-r0.aarch64", "Alpine-Linux-3.24:redis6.2-openrc-6.2.21.tuxcare.els7-r0.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2021-32625" }, { "category": "external", "summary": "https://github.com/redis/redis/releases/tag/6.0.14", "url": "https://github.com/redis/redis/releases/tag/6.0.14" }, { "category": "external", "summary": "https://github.com/redis/redis/releases/tag/6.2.4", "url": "https://github.com/redis/redis/releases/tag/6.2.4" }, { "category": "external", "summary": "https://github.com/redis/redis/security/advisories/GHSA-46cp-x4x9-6pfq", "url": "https://github.com/redis/redis/security/advisories/GHSA-46cp-x4x9-6pfq" }, { "category": "external", "summary": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BHWOF7CBVUGDK3AN6H3BN3VNTH2TDUZZ/", "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BHWOF7CBVUGDK3AN6H3BN3VNTH2TDUZZ/" }, { "category": "external", "summary": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SN7INTZFE34MIQJO7WDDTIY5LIBGN6GI/", "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SN7INTZFE34MIQJO7WDDTIY5LIBGN6GI/" } ], "release_date": "2021-06-02T20:15:00Z", "threats": [ { "category": "impact", "details": "Important" } ] } ] }
