Package : redis
Version : 5:5.0.14-1+deb10u3
CVE ID : CVE-2022-36021

It was discovered that there was a potential remote denial of service
vulnerability in redis, a popular key-value database.

Authenticated users could have used string matching commands (like
`SCAN` or `KEYS`) with a specially crafted pattern to trigger a
denial-of-service attack, causing it to hang and consume 100% CPU
time.

For Debian 10 buster, this problem has been fixed in version
5:5.0.14-1+deb10u3.

We recommend that you upgrade your redis packages.
