Vulnerability from variot
The bgp_dump_routes_func function in bgpd/bgp_dump.c in Quagga does not perform size checks when dumping data, which might allow remote attackers to cause a denial of service (assertion failure and daemon crash) via a large BGP packet. ( Statement violations and daemon crashes ) There are vulnerabilities that are put into a state.Overly large by a third party BGP Service disruption via packets ( Statement violations and daemon crashes ) There is a possibility of being put into a state. QuaggaBGPRoutingDaemon is a collection of daemons managed by the core daemon zebra, which is mainly used to exchange routing information with peer nodes running the same routing protocol. Quagga Routing Software Suite is prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause a denial-of-service condition.

Synopsis: Moderate: quagga security and bug fix update Advisory ID: RHSA-2017:0794-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0794.html Issue date: 2017-03-21 CVE Names: CVE-2013-2236 CVE-2016-1245 CVE-2016-2342 CVE-2016-4049 CVE-2017-5495 =====================================================================
- Summary:
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.
- Relevant releases/architectures:
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64
- Description:
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. (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. (CVE-2016-2342)
-
A denial of service flaw was found in the Quagga BGP routing daemon (bgpd). (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. (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.

A local user could use this issue to possibly\nobtain sensitive information. (CVE-2016-4036)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 16.04 LTS:\n quagga 0.99.24.1-2ubuntu1.1\n\nUbuntu 14.04 LTS:\n quagga 0.99.22.4-3ubuntu1.2\n\nUbuntu 12.04 LTS:\n quagga 0.99.20.1-0ubuntu0.12.04.5\n\nAfter a standard system update you need to restart Quagga to make all the\nnecessary changes. \n-----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Moderate: quagga security and bug fix update\nAdvisory ID: RHSA-2017:0794-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://rhn.redhat.com/errata/RHSA-2017-0794.html\nIssue date: 2017-03-21\nCVE Names: CVE-2013-2236 CVE-2016-1245 CVE-2016-2342 \n CVE-2016-4049 CVE-2017-5495 \n=====================================================================\n\n1. Summary:\n\nAn update for quagga is now available for Red Hat Enterprise Linux 6. \n\nRed Hat Product Security has rated this update as having a security impact\nof Moderate. A Common Vulnerability Scoring System (CVSS) base score, which\ngives a detailed severity rating, is available for each vulnerability from\nthe CVE link(s) in the References section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64\nRed Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64\nRed Hat Enterprise Linux Workstation (v. 6) - i386, x86_64\nRed Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64\n\n3. Description:\n\nThe quagga packages contain Quagga, the free network-routing software suite\nthat manages TCP/IP based protocols. Quagga supports the BGP4, BGP4+,\nOSPFv2, OSPFv3, RIPv1, RIPv2, and RIPng protocols, and is intended to be\nused as a Route Server and Route Reflector. \n\nSecurity Fix(es):\n\n* A stack-based buffer overflow flaw was found in the way Quagga handled\nIPv6 router advertisement messages. (CVE-2016-1245)\n\n* A stack-based buffer overflow flaw was found in the way the Quagga BGP\nrouting daemon (bgpd) handled Labeled-VPN SAFI routes data. (CVE-2016-2342)\n\n* A denial of service flaw was found in the Quagga BGP routing daemon\n(bgpd). \n(CVE-2016-4049)\n\n* A denial of service flaw affecting various daemons in Quagga was found. A\nremote attacker could use this flaw to cause the various Quagga daemons,\nwhich expose their telnet interface, to crash. (CVE-2017-5495)\n\n* A stack-based buffer overflow flaw was found in the way the Quagga OSPFD\ndaemon handled LSA (link-state advertisement) packets. (CVE-2013-2236)\n\nAdditional Changes:\n\nFor detailed information on changes in this release, see the Red Hat\nEnterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9\nTechnical Notes linked from the References section. \n\n4. Solution:\n\nFor details on how to apply this update, which includes the changes\ndescribed in this advisory, refer to:\n\nhttps://access.redhat.com/articles/11258\n\nAfter installing the updated packages, the bgpd daemon must be restarted\nfor the update to take effect. \n\n5.
