Updated glibc packages that fix one security issue are now available for
Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Important security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
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.
This issue was discovered by Sumit Bose and Lukáš Slebodník of Red Hat.
All glibc users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue.
