CVE-2015-8982: Integer Overflow
First published: Wed Mar 15 2017(Updated: )
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.
