How to fix?

Upgrade Debian:10 glibc to version 2.19-4 or higher.

NVD Description

Note: Versions mentioned in the description apply to the upstream glibc package. See How to fix? for Debian:10 relevant versions.

The regcomp implementation in the GNU C Library (aka glibc or libc6) through 2.11.3, and 2.12.x through 2.12.2, allows context-dependent attackers to cause a denial of service (application crash) via a regular expression containing adjacent bounded repetitions that bypass the intended RE_DUP_MAX limitation, as demonstrated by a {10,}{10,}{10,}{10,}{10,} sequence in the proftpd.gnu.c exploit for ProFTPD, related to a "RE_DUP_MAX overflow."
