CVE-2021-32687 5 Debian, Fedoraproject, Netapp and 2 more 6 Debian Linux, Fedora, Management Services For Element Software and 3 more 2024-11-21 6.0 MEDIUM 7.5 HIGH
Redis is an open source, in-memory database that persists on disk. An integer overflow bug affecting all versions of Redis can be exploited to corrupt the heap and potentially be used to leak arbitrary contents of the heap or trigger remote code execution. The vulnerability involves changing the default set-max-intset-entries configuration parameter to a very large value and constructing specially crafted commands to manipulate sets. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the set-max-intset-entries configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.
CVE-2021-32675 5 Debian, Fedoraproject, Netapp and 2 more 6 Debian Linux, Fedora, Management Services For Element Software and 3 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Redis is an open source, in-memory database that persists on disk. When parsing an incoming Redis Standard Protocol (RESP) request, Redis allocates memory according to user-specified values which determine the number of elements (in the multi-bulk header) and size of each element (in the bulk header). An attacker delivering specially crafted requests over multiple connections can cause the server to allocate significant amount of memory. Because the same parsing mechanism is used to handle authentication requests, this vulnerability can also be exploited by unauthenticated users. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate this problem without patching the redis-server executable is to block access to prevent unauthenticated users from connecting to Redis. This can be done in different ways: Using network access control tools like firewalls, iptables, security groups, etc. or Enabling TLS and requiring users to authenticate using client side certificates.
CVE-2021-32672 6 Debian, Fedoraproject, Netapp and 3 more 8 Debian Linux, Fedora, Management Services For Element Software and 5 more 2024-11-21 4.0 MEDIUM 5.3 MEDIUM
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.
CVE-2021-32628 5 Debian, Fedoraproject, Netapp and 2 more 6 Debian Linux, Fedora, Management Services For Element Software and 3 more 2024-11-21 6.0 MEDIUM 7.5 HIGH
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. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.
CVE-2021-32627 5 Debian, Fedoraproject, Netapp and 2 more 6 Debian Linux, Fedora, Management Services For Element Software and 3 more 2024-11-21 6.0 MEDIUM 7.5 HIGH
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. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.
CVE-2021-32626 5 Debian, Fedoraproject, Netapp and 2 more 6 Debian Linux, Fedora, Management Services For Element Software and 3 more 2024-11-21 6.5 MEDIUM 7.5 HIGH
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. For users unable to update an additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to restrict EVAL and EVALSHA commands.
CVE-2023-41056 2 Fedoraproject, Redis 2 Fedora, Redis 2024-02-28 N/A 8.1 HIGH
Redis is an in-memory database that persists on disk. Redis incorrectly handles resizing of memory buffers which can result in integer overflow that leads to heap overflow and potential remote code execution. This issue has been patched in version 7.0.15 and 7.2.4.
CVE-2023-31654 1 Redis 1 Redisraft 2024-02-28 N/A 9.8 CRITICAL
Redis raft master-1b8bd86 to master-7b46079 was discovered to contain an ODR violation via the component hiredisAllocFns at /opt/fs/redisraft/deps/hiredis/alloc.c.
CVE-2021-31294 1 Redis 1 Redis 2024-02-28 N/A 5.9 MEDIUM
Redis before 6cbea7d allows a replica to cause an assertion failure in a primary server by sending a non-administrative command (specifically, a SET command). NOTE: this was fixed for Redis 6.2.x and 7.x in 2021. Versions before 6.2 were not intended to have safety guarantees related to this.
CVE-2022-24834 2 Fedoraproject, Redis 2 Fedora, Redis 2024-02-28 N/A 8.8 HIGH
Redis is an in-memory database that persists on disk. A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson library, and result with heap corruption and potentially remote code execution. The problem exists in all versions of Redis with Lua scripting support, starting from 2.6, and affects only authenticated and authorized users. The problem is fixed in versions 7.0.12, 6.2.13, and 6.0.20.
CVE-2023-45145 3 Debian, Fedoraproject, Redis 3 Debian Linux, Fedora, Redis 2024-02-28 N/A 3.6 LOW
Redis is an in-memory database that persists on disk. On startup, Redis begins listening on a Unix socket before adjusting its permissions to the user-provided configuration. If a permissive umask(2) is used, this creates a race condition that enables, during a short period of time, another process to establish an otherwise unauthorized connection. This problem has existed since Redis 2.6.0-RC1. This issue has been addressed in Redis versions 7.2.2, 7.0.14 and 6.2.14. Users are advised to upgrade. For users unable to upgrade, it is possible to work around the problem by disabling Unix sockets, starting Redis with a restrictive umask, or storing the Unix socket file in a protected directory.
CVE-2023-41053 1 Redis 1 Redis 2024-02-28 N/A 3.3 LOW
Redis is an in-memory database that persists on disk. Redis does not correctly identify keys accessed by `SORT_RO` and as a result may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. The problem exists in Redis 7.0 or newer and has been fixed in Redis 7.0.13 and 7.2.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-36824 2 Fedoraproject, Redis 2 Fedora, Redis 2024-02-28 N/A 8.8 HIGH
Redis is an in-memory database that persists on disk. In Redit 7.0 prior to 7.0.12, extracting key names from a command and a list of arguments may, in some cases, trigger a heap overflow and result in reading random heap memory, heap corruption and potentially remote code execution. Several scenarios that may lead to authenticated users executing a specially crafted `COMMAND GETKEYS` or `COMMAND GETKEYSANDFLAGS`and authenticated users who were set with ACL rules that match key names, executing a specially crafted command that refers to a variadic list of key names. The vulnerability is patched in Redis 7.0.12.
