https://notcve.org/view.php?id=CVE-2022-3647
** DISPUTED ** A vulnerability, which was classified as problematic, was found in Redis up to 6.2.7/7.0.5. Affected is the function sigsegvHandler of the file debug.c of the component Crash Report. The manipulation leads to denial of service. The complexity of an attack is rather high. The exploitability is told to be difficult. • https://github.com/redis/redis/commit/0bf90d944313919eb8e63d3588bf63a367f020a3 https://vuldb.com/?ctiid.211962 https://vuldb.com/?id.211962 • CWE-404: Improper Resource Shutdown or Release •
CVSS: 5.5EPSS: 0%CPEs: 12EXPL: 1CVE-2022-24736 – A Malformed Lua script can crash Redis
https://notcve.org/view.php?id=CVE-2022-24736
Redis is an in-memory database that persists on disk. Prior to versions 6.2.7 and 7.0.0, an attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result with a crash of the redis-server process. The problem is fixed in Redis versions 7.0.0 and 6.2.7. An additional workaround to mitigate this problem without patching the redis-server executable, if Lua scripting is not being used, is to block access to `SCRIPT LOAD` and `EVAL` commands using ACL rules. Redis es una base de datos en memoria que persiste en el disco. • https://github.com/redis/redis/pull/10651 https://github.com/redis/redis/releases/tag/6.2.7 https://github.com/redis/redis/releases/tag/7.0.0 https://github.com/redis/redis/security/advisories/GHSA-3qpw-7686-5984 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J4ZK3675DGHVVDOFLJN7WX6YYH27GPMK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VPYKSG7LKUJGVM2P72EHXKVRVRWHLORX https://lists.fedoraproject.org/archives/list/ • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 1CVE-2022-24735 – Lua scripts can be manipulated to overcome ACL rules in Redis
https://notcve.org/view.php?id=CVE-2022-24735
Redis is an in-memory database that persists on disk. By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis prior to version 7.0.0 or 6.2.7 can inject Lua code that will execute with the (potentially higher) privileges of another Redis user. The Lua script execution environment in Redis provides some measures that prevent a script from creating side effects that persist and can affect the execution of the same, or different script, at a later time. Several weaknesses of these measures have been publicly known for a long time, but they had no security impact as the Redis security model did not endorse the concept of users or privileges. With the introduction of ACLs in Redis 6.0, these weaknesses can be exploited by a less privileged users to inject Lua code that will execute at a later time, when a privileged user executes a Lua script. • https://github.com/redis/redis/pull/10651 https://github.com/redis/redis/releases/tag/6.2.7 https://github.com/redis/redis/releases/tag/7.0.0 https://github.com/redis/redis/security/advisories/GHSA-647m-2wmq-qmvq https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J4ZK3675DGHVVDOFLJN7WX6YYH27GPMK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VPYKSG7LKUJGVM2P72EHXKVRVRWHLORX https://lists.fedoraproject.org/archives/list/ • CWE-94: Improper Control of Generation of Code ('Code Injection') •
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 •
CVSS: 7.5EPSS: 1%CPEs: 8EXPL: 0CVE-2021-32761 – Integer overflow issues with *BIT commands on 32-bit systems
https://notcve.org/view.php?id=CVE-2021-32761
Redis is an in-memory database that persists on disk. A vulnerability involving out-of-bounds read and integer overflow to buffer overflow exists starting with version 2.2 and prior to versions 5.0.13, 6.0.15, and 6.2.5. On 32-bit systems, Redis `*BIT*` command are vulnerable to integer overflow that can potentially be exploited to corrupt the heap, leak arbitrary heap contents or trigger remote code execution. The vulnerability involves changing the default `proto-max-bulk-len` configuration parameter to a very large value and constructing specially crafted commands bit commands. This problem only affects Redis on 32-bit platforms, or compiled as a 32-bit binary. • https://github.com/redis/redis/security/advisories/GHSA-8wxq-j7rp-g8wj https://lists.debian.org/debian-lts-announce/2021/07/msg00017.html https://lists.debian.org/debian-lts-announce/2021/08/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6O7AUOROBYGP5IMGJPC5HZ3R2RB6GZ5X https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VGX7RRAWGXWXEAKJTQYSDSBO2BC3SAHD https://security.gentoo.org/glsa/202209-17 https://security.netapp&# • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •
