CVE-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 •
CVE-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 •
CVE-2021-32625 – Redis vulnerability in STRALGO LCS on 32-bit systems
https://notcve.org/view.php?id=CVE-2021-32625
Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. 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. • https://github.com/redis/redis/releases/tag/6.0.14 https://github.com/redis/redis/releases/tag/6.2.4 https://github.com/redis/redis/security/advisories/GHSA-46cp-x4x9-6pfq https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BHWOF7CBVUGDK3AN6H3BN3VNTH2TDUZZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SN7INTZFE34MIQJO7WDDTIY5LIBGN6GI • CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •
CVE-2021-29478 – Vulnerability in the COPY command for large intsets
https://notcve.org/view.php?id=CVE-2021-29478
Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. An integer overflow bug in Redis 6.2 before 6.2.3 could be exploited to corrupt the heap and potentially result with remote code execution. Redis 6.0 and earlier are not directly affected by this issue. The problem is fixed in version 6.2.3. 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. • https://github.com/redis/redis/security/advisories/GHSA-qh52-crrg-44g3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BPWBIZXA67JFIB63W2CNVVILCGIC2ME5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EZJ6JGQ2ETZB2DWTQSGCOGG7EF3ILV4V https://redis.io https://security.gentoo.org/glsa/202107-20 https://access.redhat.com/security/cve/CVE-2021-29478 https://bugzilla.redhat.com/show_bug.cgi?id=1957414 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
