red hat
Calendar Grey November 5, 2019
Dist Redhat Esm H88
Debian issues a new version for libssl classified as moderate; crucial patches and improvements incorporated.
An update for glibc is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Moderate

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: getaddrinfo should reject IP addresses with trailing characters (CVE-2016-10739)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
