RHEL 6 : quagga (RHSA-2017:0794)

critical Nessus Plugin ID 97885

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:0794 advisory.

The quagga packages contain Quagga, the free network-routing software suite that manages TCP/IP based protocols. Quagga supports the BGP4, BGP4+, OSPFv2, OSPFv3, RIPv1, RIPv2, and RIPng protocols, and is intended to be used as a Route Server and Route Reflector.

Security Fix(es):

* A stack-based buffer overflow flaw was found in the way Quagga handled IPv6 router advertisement messages. A remote attacker could use this flaw to crash the zebra daemon resulting in denial of service.
(CVE-2016-1245)

* A stack-based buffer overflow flaw was found in the way the Quagga BGP routing daemon (bgpd) handled Labeled-VPN SAFI routes data. A remote attacker could use this flaw to crash the bgpd daemon resulting in denial of service. (CVE-2016-2342)

* A denial of service flaw was found in the Quagga BGP routing daemon (bgpd). Under certain circumstances, a remote attacker could send a crafted packet to crash the bgpd daemon resulting in denial of service.
(CVE-2016-4049)

* A denial of service flaw affecting various daemons in Quagga was found. A remote attacker could use this flaw to cause the various Quagga daemons, which expose their telnet interface, to crash. (CVE-2017-5495)

* A stack-based buffer overflow flaw was found in the way the Quagga OSPFD daemon handled LSA (link-state advertisement) packets. A remote attacker could use this flaw to crash the ospfd daemon resulting in denial of service. (CVE-2013-2236)

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9 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 quagga package based on the guidance in RHSA-2017:0794.
