Synopsis

Moderate: quagga security and bug fix update

Type/Severity

Security Advisory: Moderate

Topic

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.

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. 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.
