"According to the versions of the quagga package installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - A double-free vulnerability was found in Quagga. A BGP
    peer could send a specially crafted UPDATE message
    which would cause allocated blocks of memory to be
    free()d more than once, potentially leading to a crash
    or other issues.(CVE-2018-5379)

  - All versions of Quagga, 0.93 through 1.1.0, are
    vulnerable to an unbounded memory allocation in the
    telnet 'vty' CLI, leading to a Denial-of-Service of
    Quagga daemons, or even the entire host. When Quagga
    daemons are configured with their telnet CLI enabled,
    anyone who can connect to the TCP ports can trigger
    this vulnerability, prior to authentication. Most
    distributions restrict the Quagga telnet interface to
    local access only by default. The Quagga telnet
    interface 'vty' input buffer grows automatically,
    without bound, so long as a newline is not entered.
    This allows an attacker to cause the Quagga daemon to
    allocate unbounded memory by sending very long strings
    without a newline. Eventually the daemon is terminated
    by the system, or the system itself runs out of
    memory.(CVE-2017-5495)

"This update for quagga fixes the following security issues :

  - The Quagga BGP daemon contained a bug in the AS_PATH
    size calculation that could have been exploited to
    facilitate a remote denial-of-service attack via
    specially crafted BGP UPDATE messages. [CVE-2017-16227,
    bsc#1065641]

  - The Quagga BGP daemon did not check whether data sent to
    peers via NOTIFY had an invalid attribute length. It was
    possible to exploit this issue and cause the bgpd
    process to leak sensitive information over the network
    to a configured peer. [CVE-2018-5378, bsc#1079798]

  - The Quagga BGP daemon used to double-free memory when
    processing certain forms of UPDATE messages. This issue
    could be exploited by sending an optional/transitive
    UPDATE attribute that all conforming eBGP speakers
    should pass along. Consequently, a single UPDATE message
    could have affected many bgpd processes across a wide
    area of a network. Through this vulnerability, attackers
    could potentially have taken over control of affected
    bgpd processes remotely. [CVE-2018-5379, bsc#1079799]

  - It was possible to overrun internal BGP code-to-string
    conversion tables in the Quagga BGP daemon. Configured
    peers could have exploited this issue and cause bgpd to
    emit debug and warning messages into the logs that would
    contained arbitrary bytes. [CVE-2018-5380, bsc#1079800]

  - The Quagga BGP daemon could have entered an infinite
    loop if sent an invalid OPEN message by a configured
    peer. If this issue was exploited, then bgpd would cease
    to respond to any other events. BGP sessions would have
    been dropped and not be reestablished. The CLI interface
    would have been unresponsive. The bgpd daemon would have
    stayed in this state until restarted. [CVE-2018-5381,
    bsc#1079801]

  - The Quagga daemon's telnet 'vty' CLI contains an
    unbounded memory allocation bug that could be exploited
    for a denial-of-service attack on the daemon. This issue
    has been fixed. [CVE-2017-5495, bsc#1021669]

  - The telnet 'vty' CLI of the Quagga daemon is no longer
    enabled by default, because the passwords in the default
    'zebra.conf' config file are now disabled. The vty
    interface is available via 'vtysh' utility using pam
    authentication to permit management access for root
    without password. [bsc#1021669]

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible

"An update for quagga is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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)

Enterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9

"This update for quagga to version 1.1.1 fixes the following issues :

This security issue was fixed :

  - CVE-2017-5495: Quagga was vulnerable to an unbounded
    memory allocation in the telnet 'vty' CLI, leading to a
    Denial-of-Service of Quagga daemons, or even the entire
    host. When Quagga daemons are configured with their
    telnet CLI enabled, anyone who can connect to the TCP
    ports can trigger this vulnerability, prior to
    authentication (bsc#1021669).

These non-security issues were fixed :

  - Disabled passwords in default zebra.conf config file,
    causing to disable vty telnet interface by default. The
    vty interface is available via 'vtysh' utility using pam
    authentication to permit management access for root
    without password (boo#1021669).

  - Changed owner of /etc/quagga to quagga:quagga to permit
    to manage quagga via vty interface.

  - Added quagga.log and create and su statemets to
    logrotate config, changed default zebra log file name
    from quagga.log to zebra.log.

  - Added libfpm_pb0 and libquagga_pb0 shared library
    sub-packages, adjusted libzebra0 sub-package name to
    libzebra1.

  - Do not enable zebra's tcp interface (port 2600) to use
    default unix socket for communication between the
    daemons 

A digest of the other changes by the version upgrade :

  - isisd: Fix size of malloc

  - isisd: check for the existance of the correct list

  - ospf6d: fix off-by-one on display of spf reasons

  - ospf6d: don't access nexthops out of bounds

  - bgpd: fix off-by-one in attribute flags handling

  - bgpd: Fix buffer overflow error in bgp_dump_routes_func

"From Red Hat Security Advisory 2017:0794 :

An update for quagga is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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)
