5.5MEDIUM
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
