RHEL 6 / 7 : nss (RHSA-2017:2832)

high Nessus Plugin ID 103562

Language:

Synopsis

The remote Red Hat host is missing a security update for nss.

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2832 advisory.

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications.

Security Fix(es):

* A use-after-free flaw was found in the TLS 1.2 implementation in the NSS library when client authentication was used. A malicious client could use this flaw to cause an application compiled against NSS to crash or, potentially, execute arbitrary code with the permission of the user running the application. (CVE-2017-7805)

Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Martin Thomson as the original reporter.

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

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

Solution

Update the RHEL nss package based on the guidance in RHSA-2017:2832.
