Scientific Linux Security Update : glibc on SL6.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

The glibc packages contain the standard C libraries used by multiple
programs on the system. These packages contain the standard C and the
standard math libraries. Without these two libraries, a Linux system
cannot function properly.

A flaw was found in the way the ldd utility identified dynamically
linked libraries. If an attacker could trick a user into running ldd
on a malicious binary, it could result in arbitrary code execution
with the privileges of the user running ldd. (CVE-2009-5064)

It was found that the glibc addmntent() function, used by various
mount helper utilities, did not handle certain errors correctly when
updating the mtab (mounted file systems table) file. If such utilities
had the setuid bit set, a local attacker could use this flaw to
corrupt the mtab file. (CVE-2011-1089)

This update also fixes several bugs and adds various enhancements.

Users are advised to upgrade to these updated glibc packages, which
contain backported patches to resolve these issues and add these
enhancements.
