CVE-2021-32626 – Lua scripts can overflow the heap-based Lua stack in Redis
https://notcve.org/view.php?id=CVE-2021-32626
04 Oct 2021 — 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 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
