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 •
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 •

https://notcve.org/view.php?id=CVE-2021-3470
A heap overflow issue was found in Redis in versions before 5.0.10, before 6.0.9 and before 6.2.0 when using a heap allocator other than jemalloc or glibc's malloc, leading to potential out of bound write or process crash. Effectively this flaw does not affect the vast majority of users, who use jemalloc or glibc malloc. Se encontró un problema de desbordamiento de pila en Redis en las versiones anteriores a 5.0.10, versiones anteriores a 6.0.9 y versiones anteriores a 6.2.0, cuando se usaba un asignador de pila que no fuera jemalloc o malloc de glibc, conllevando a un posible bloqueo del proceso o de escritura fuera de límites. Efectivamente, este fallo no afecta a la gran mayoría de usuarios que usan jemalloc o glibc malloc. • https://bugzilla.redhat.com/show_bug.cgi?id=1943623 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-21309
Redis is an open-source, in-memory database that persists on disk. In affected versions of Redis an integer overflow bug in 32-bit Redis version 4.0 or newer could be exploited to corrupt the heap and potentially result with remote code execution. Redis 4.0 or newer uses a configurable limit for the maximum supported bulk input size. By default, it is 512MB which is a safe value for all platforms. If the limit is significantly increased, receiving a large request from a client may trigger several integer overflow scenarios, which would result with buffer overflow and heap corruption. • https://github.com/redis/redis/commit/c992857618db99776917f10bf4f2345a5fdc78b0 https://github.com/redis/redis/pull/8522 https://github.com/redis/redis/security/advisories/GHSA-hgj8-vff2-7cjf https://security.gentoo.org/glsa/202103-02 https://access.redhat.com/security/cve/CVE-2021-21309 https://bugzilla.redhat.com/show_bug.cgi?id=1932634 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-190: Integer Overflow or Wraparound •
