CVE Details

Release Date:	2014-02-21
Impact:	Low	What is this?

Description

The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (akaglibc 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.
