CVE-2015-8982: GNU Glibc

High severity, CVSS 8.1. EPSS: 3.8% chance of exploitation in the next 30 days.

Integer overflow in the strxfrm function in the GNU C Library (aka glibc or libc6) before 2.21 allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow.

Affected products

• GNU Glibc: up to and including 2.20
