CWE-122  (opens in a new tab)

How to fix?

Upgrade Centos:7 glibc-common to version 0:2.17-105.el7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-common package and not the glibc-common 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 memory allocation, which allows context-dependent attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a long line containing wide characters that are improperly handled in a wscanf call.
