How to fix?

Upgrade Debian:10 glibc to version 2.3.5-3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The getgrouplist function in the GNU C library (glibc) before version 2.3.5, when invoked with a zero argument, writes to the passed pointer even if the specified array size is zero, leading to a buffer overflow and potentially allowing attackers to corrupt memory.
