TITLE

Quagga BGPD Local Denial Of Service Vulnerability

DESCRIPTION

bgpd in Quagga 0.98 and 0.99 before 20060504 allows local users to cause a denial of service (CPU consumption) via a certain sh ip bgp command entered in the telnet interface. ------------ This vulnerability information is a summary of multiple vulnerabilities released at the same time. Please note that the contents of vulnerability information other than the title are included. ------------ Quagga , GNU Zebra Is TCP/IP A collection of daemons that support base routing related protocols. Out of them RIP , BGP As a daemon that handles the protocol RIPd , bgpd Is included. Quagga , GNU Zebra Has several security issues: 1) RIPd The daemon RIPv2 Even if the setting is valid only, regardless of the presence or absence of authentication RIPv1 There is a problem that responds to the request. (CVE-2006-2223) If exploited by a remote attacker, SEND UPDATE Such as REQUEST Routing information may be obtained illegally by using packets. 2) RIPd The daemon RIPv2 Despite being enabled for authentication, RIPv1 There is a problem of accepting packets without authentication. (CVE-2006-2224) If exploited by a remote attacker, RIPv1 of RESPONSE By using packet RIP The routing table may be modified incorrectly. (CVE-2006-2276) If exploited by a local attacker, the target system can eventually become unserviceable.Please refer to the “Overview” for the impact of this vulnerability. Quagga is prone to a local denial-of-service vulnerability. An attacker can exploit this issue by using commands that cause the consumption of a large amount of CPU resources. An attacker may cause the application to crash, thus denying service to legitimate users. Version 0.98.3 is vulnerable; other versions may also be affected. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 1059-1 security@debian.org http://www.debian.org/security/ Martin Schulze May 19th, 2006 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : quagga Vulnerability : several Problem type : remote Debian-specific: no CVE IDs : CVE-2006-2223 CVE-2006-2224 CVE-2006-2276 BugTraq ID : 17808 Debian Bugs : 365940 366980 Konstantin Gavrilenko discovered several vulnerabilities in quagga, the BGP/OSPF/RIP routing daemon. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2006-2223 Remote attackers may obtain sensitive information via RIPv1 REQUEST packets even if the quagga has been configured to use MD5 authentication. CVE-2006-2224 Remote attackers could inject arbitrary routes using the RIPv1 RESPONSE packet even if the quagga has been configured to use MD5 authentication. The old stable distribution (woody) does not contain quagga packages. For the stable distribution (sarge) these problems have been fixed in version 0.98.3-7.2. For the unstable distribution (sid) these problems have been fixed in version 0.99.4-1. We recommend that you upgrade your quagga package.

The BGP daemon is vulnerable to a Denial of Service. Background ========== The Quagga Routing Suite implements three major routing protocols: RIP (v1/v2/v3), OSPF (v2/v3) and BGP4. Gavrilenko discovered two flaws in the Routing Information Protocol (RIP) daemon that allow the processing of RIP v1 packets (carrying no authentication) even when the daemon is configured to use MD5 authentication or, in another case, even if RIP v1 is completely disabled. Workaround ========== There is no known workaround at this time. Resolution ========== All Quagga users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/quagga-0.98.6-r1" References ========== [ 1 ] CVE-2006-2223 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2223 [ 2 ] CVE-2006-2224 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2224 [ 3 ] CVE-2006-2276 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2276 [ 4 ] Official release information http://www.quagga.net/news2.php?y=2006&m=5&d=8#id1147115280 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200605-15.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
