CVE-2015-1473

Priority
Description
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.
