Test ID:1.3.6.1.4.1.25623.1.0.871484
Category:Red Hat Local Security Checks
Title:RedHat Update for glibc RHSA-2015:2172-01
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.

It was discovered that the nss_files backend for the Name Service Switch in
glibc would return incorrect data to applications or corrupt the heap
(depending on adjacent heap contents) in certain cases. A local attacker
could potentially use this flaw to escalate their privileges.
(CVE-2015-5277)

This issue was discovered by Sumit Bose and Luk Slebodnk of Red Hat.

All glibc users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue.

Affected Software/OS:
glibc on Red Hat Enterprise Linux Server (v. 7)

Solution:
Please Install the Updated Packages.

CVSS Score:
