Scientific Linux Security Update : glibc on SL7.x x86_64 (20141218)

medium Nessus Plugin ID 80162
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.

Solution

Update the affected packages.
