Description

nscd in the GNU C Library (aka glibc or libc6) before version 2.20 does not correctly compute the size of an internal buffer when processing netgroup requests, possibly leading to an nscd daemon crash or code execution as the user running nscd.

Statement

This issue did not affect the versions of glibc as shipped with Red Hat Enterprise Linux 5 as they did not include support for netgroups. Red Hat Enterprise Linux 6 and 7 already include the fixed version of the package.
