NVD Description

Note: Versions mentioned in the description apply only to the upstream redis:6/redis-doc package and not the redis:6/redis-doc package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
