- CWE-119
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.
Affected configurations
• canonical ubuntu linux 10.04
• canonical ubuntu linux 12.04
• canonical ubuntu linux 14.04
• canonical ubuntu linux 14.10
• gnu glibc (<= 2.20)
