Scientific Linux Security Update : glibc on SL7.x x86_64

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

It was found that the wordexp() function would perform command
substitution even when the WRDE_NOCMD flag was specified. An attacker
able to provide specially crafted input to an application using the
wordexp() function, and not sanitizing the input correctly, could
potentially use this flaw to execute arbitrary commands with the
credentials of the user running that application. (CVE-2014-7817)

This update also fixes the following bug :

- Prior to this update, if a file stream that was opened
in append mode and its underlying file descriptor were
used at the same time and the file was truncated using
the ftruncate() function on the file descriptor, a
subsequent ftell() call on the stream incorrectly
modified the file offset by seeking to the new end of
the file. This update ensures that ftell() modifies the
state of the file stream only when it is in append mode
and its buffer is not empty. As a result, the described
incorrect changes to the file offset no longer occur.
