RHEL 6 : glibc (RHSA-2018:1879)

critical Nessus Plugin ID 110603

Synopsis

The remote Red Hat host is missing one or more security updates for glibc.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1879 advisory.

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:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.10 Release Notes and Red Hat Enterprise Linux 6.10 Technical Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL glibc package based on the guidance in RHSA-2018:1879.
