SUSE SLES12 Security Update : glibc (SUSE-SU-2018:0076-1)

critical Nessus Plugin ID 106046
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for glibc fixes the following issues :

- A privilege escalation bug in the realpath() function has been fixed. [CVE-2018-1000001, bsc#1074293]

- A buffer manipulation vulnerability in nscd has been fixed that could possibly have lead to an nscd daemon crash or code execution as the user running nscd.
[CVE-2014-9984, bsc#1043984]

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
