RHEL 6 RHSA-2018-1879-01 Moderate: glibc Buffer Overflow Security Fix

red hat
Calendar Grey June 19, 2018
Scroller Redhat
Ubuntu releases an important OpenSSL upgrade addressing multiple vulnerabilities. Critical for maintaining the integrity and safety of server environments.
An update for glibc is now available for Red Hat Enterprise Linux 6

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all services linked to the glibc library must be restarted, or the system rebooted.

Summary

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the name service cache daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.
Security Fix(es):
* glibc: Buffer overflow in glob with GLOB_TILDE (CVE-2017-15670)
* glibc: Buffer overflow during unescaping of user names with the ~ operator (CVE-2017-15804)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes:
