CVSS 3.0
8.1 highCVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2015-8983
High (8.1) in gnu glibc. EPSS 4.0% chance of exploitation in the next 30 days.
Integer overflow in the _IO_wstr_overflow function in libio/wstrops.c in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors related to computing a size in bytes, which triggers a heap-based buffer overflow.
