CVSS: 5.3EPSS: 0%CPEs: 15EXPL: 0CVE-2021-32672 – Vulnerability in Lua Debugger in Redis
https://notcve.org/view.php?id=CVE-2021-32672
Redis is an open source, in-memory database that persists on disk. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support (3.2 or newer). The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. Redis es una base de datos en memoria de código abierto que persiste en el disco. • https://github.com/redis/redis/commit/6ac3c0b7abd35f37201ed2d6298ecef4ea1ae1dd https://github.com/redis/redis/security/advisories/GHSA-9mj9-xx53-qmxm https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB https://security.gentoo.org/gls • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-2021-32627 – Integer overflow issue with Streams in Redis
https://notcve.org/view.php?id=CVE-2021-32627
Redis is an open source, in-memory database that persists on disk. 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. • https://github.com/redis/redis/commit/f6a40570fa63d5afdd596c78083d754081d80ae3 https://github.com/redis/redis/security/advisories/GHSA-f434-69fm-g45v https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB https://security.gentoo.org/gls • CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-2021-32628 – Vulnerability in handling large ziplists
https://notcve.org/view.php?id=CVE-2021-32628
Redis is an open source, in-memory database that persists on disk. An integer overflow bug in the ziplist data structure used by all versions of Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves modifying the default ziplist configuration parameters (hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries or zset-max-ziplist-value) to a very large value, and then constructing specially crafted commands to create very large ziplists. The problem is fixed in Redis versions 6.2.6, 6.0.16, 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the above configuration parameters. • https://github.com/redis/redis/commit/f6a40570fa63d5afdd596c78083d754081d80ae3 https://github.com/redis/redis/security/advisories/GHSA-vw22-qm3h-49pr https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB https://security.gentoo.org/gls • CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 2%CPEs: 13EXPL: 0CVE-2021-32626 – Lua scripts can overflow the heap-based Lua stack in Redis
https://notcve.org/view.php?id=CVE-2021-32626
Redis is an open source, in-memory database that persists on disk. In affected versions specially crafted Lua scripts executing in Redis can cause the heap-based Lua stack to be overflowed, due to incomplete checks for this condition. This can result with heap corruption and potentially remote code execution. This problem exists in all versions of Redis with Lua scripting support, starting from 2.6. The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. • https://github.com/redis/redis/commit/666ed7facf4524bf6d19b11b20faa2cf93fdf591 https://github.com/redis/redis/security/advisories/GHSA-p486-xggp-782c https://lists.apache.org/thread.html/r75490c61c2cb7b6ae2c81238fd52ae13636c60435abcd732d41531a0%40%3Ccommits.druid.apache.org%3E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/arch • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
