Package : redis
Version : 5:5.0.14-1+deb10u4
CVE ID : CVE-2023-28856
Debian Bug : 1034613

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

Authenticated users could have used the `HINCRBYFLOAT` command to
create an invalid hash field that would have crashed the Redis server
on access.

For Debian 10 buster, this problem has been fixed in version
5:5.0.14-1+deb10u4.

We recommend that you upgrade your redis packages.
