Title:	RedHat Update for glibc RHSA-2015:0863-01
Summary:	The remote host is missing an update for the 'glibc'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'glibc' package(s) announced via the referenced advisory. Vulnerability Insight: The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. A buffer overflow flaw was found in the way glibc's gethostbyname_r() and other related functions computed the size of a buffer when passed a misaligned buffer as input. An attacker able to make an application call any of these functions with a misaligned buffer could use this flaw to crash the application or, potentially, execute arbitrary code with the permissions of the user running the application. (CVE-2015-1781) It was discovered that, under certain circumstances, glibc's getaddrinfo() function would send DNS queries to random file descriptors. An attacker could potentially use this flaw to send DNS queries to unintended recipients, resulting in information disclosure or data loss due to the application encountering corrupted data. (CVE-2013-7423) The CVE-2015-1781 issue was discovered by Arjun Shankar of Red Hat. This update also fixes the following bug: * Previously, the nscd daemon did not properly reload modified data when the user edited monitored nscd configuration files. As a consequence, nscd returned stale data to system processes. This update adds a system of inotify-based monitoring and stat-based backup monitoring for nscd configuration files. As a result, nscd now detects changes to its configuration files and reloads the data properly, which prevents it from returning stale data. (BZ#1194149) All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. Affected Software/OS: glibc on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages.
