How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-static package and not the glibc-static package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boundary via a long line containing wide characters that are improperly handled in a wscanf call.
