The remote NewStart CGSL host, running version MAIN 4.05, has quagga packages installed that are affected by multiple vulnerabilities:
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 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 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 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 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)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
