CVE-2015-1472

UnknownEPSS 4.69%

Last modified

CVE-2015-1472 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 4.69% chance of exploitation in the next 30 days.
