CVE-2014-9761 introduced a regression which affected applications that
use the libm library but were not fully restarted after the upgrade.

glibc: Unbounded stack allocation in nan* functions
Multiple stack-based buffer overflows in the GNU C Library (aka glibc or libc6) before 2.23 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long argument to the (1) nan, (2) nanf, or (3) nanl function.
A stack overflow vulnerability was found in nan* functions that could cause applications, which process long strings with the nan function, to crash or, potentially, execute arbitrary code.
Mitigation: Do not use any applications which call the affected nan* functions. These functions are used only very rarely.
