What is CVE-2022-35977?

Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted SETRANGE and SORT(_RO) commands can trigger an integer overflow, resulting with Redis attempting to allocate impossible amounts of memory and abort with an out-of-memory (OOM) panic. The problem is fixed in Redis versions 7.0.8, 6.2.9 and 6.0.17. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Affected Version(s)

redis >= 7.0, < 7.0.8 < 7.0, 7.0.8

redis >= 6.2, < 6.2.9 < 6.2, 6.2.9

redis < 6.0.17 < 6.0.17
