How to fix?

Upgrade Debian:9 libgc to version 1:7.1-9 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libgc package and not the libgc package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

Multiple integer overflows in the (1) GC_generic_malloc and (2) calloc functions in malloc.c, and the (3) GC_generic_malloc_ignore_off_page function in mallocx.c in Boehm-Demers-Weiser GC (libgc) before 7.2 make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which causes less memory to be allocated than expected.
