CVE-2015-1473

glibc: Stack-overflow in glibc swscanf

Published Apr 8, 2015 CVSS 2.0 · 6.4 Medium EPSS 2.1% KEV · Not listed
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.
