TITLE

Quagga of bgpd Service disruption in Null Pointer dereference and application crash vulnerabilities

DESCRIPTION

The extended-community parser in bgpd in Quagga before 0.99.18 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a malformed Extended Communities attribute. Quagga is prone to a remote denial-of-service vulnerability caused by a NULL-pointer dereference in the Border Gateway Protocol daemon (bgpd). - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201202-02 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: Quagga: Multiple vulnerabilities Date: February 21, 2012 Bugs: #334303, #359903, #384651 ID: 201202-02 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities were found in Quagga, the worst of which leading to remote execution of arbitrary code.

The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: quagga 0.99.2-1ubuntu3.8 Ubuntu 8.04 LTS: quagga 0.99.9-2ubuntu1.5 Ubuntu 9.10: quagga 0.99.13-1ubuntu0.2 Ubuntu 10.04 LTS: quagga 0.99.15-1ubuntu0.2 Ubuntu 10.10: quagga 0.99.17-1ubuntu0.1 In general, a standard system update will make all the necessary changes. Details follow: It was discovered that Quagga incorrectly parsed certain malformed extended communities. A remote attacker could use this flaw to disrupt BGP sessions, resulting in a denial of service. This issue only affected Ubuntu 8.04 LTS, 9.10, 10.04 LTS and 10.10.

===================================================================== Red Hat Security Advisory Synopsis: Moderate: quagga security update Advisory ID: RHSA-2012:1258-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1258.html Issue date: 2012-09-12 CVE Names: CVE-2010-1674 CVE-2011-3323 CVE-2011-3324 CVE-2011-3325 CVE-2011-3326 CVE-2011-3327 CVE-2012-0249 CVE-2012-0250 ===================================================================== 1. Summary: Updated quagga packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: Quagga is a TCP/IP based routing software suite. The Quagga ospfd and ospf6d daemons implement the OSPF (Open Shortest Path First) routing protocol. A heap-based buffer overflow flaw was found in the way the bgpd daemon processed malformed Extended Communities path attributes. An attacker could send a specially-crafted BGP message, causing bgpd on a target system to crash or, possibly, execute arbitrary code with the privileges of the user running bgpd. The UPDATE message would have to arrive from an explicitly configured BGP peer, but could have originated elsewhere in the BGP network. A configured BGP peer could crash bgpd on a target system via a specially-crafted BGP message. (CVE-2010-1674) A stack-based buffer overflow flaw was found in the way the ospf6d daemon processed malformed Link State Update packets. An OSPF router could use this flaw to crash ospf6d on an adjacent router. (CVE-2011-3323) A flaw was found in the way the ospf6d daemon processed malformed link state advertisements. An OSPF neighbor could use this flaw to crash ospf6d on a target system. (CVE-2011-3324) A flaw was found in the way the ospfd daemon processed malformed Hello packets. An OSPF neighbor could use this flaw to crash ospfd on a target system. (CVE-2011-3325) A flaw was found in the way the ospfd daemon processed malformed link state advertisements. An OSPF router in the autonomous system could use this flaw to crash ospfd on a target system. (CVE-2011-3326) An assertion failure was found in the way the ospfd daemon processed certain Link State Update packets. An OSPF router could use this flaw to cause ospfd on an adjacent router to abort. (CVE-2012-0249) A buffer overflow flaw was found in the way the ospfd daemon processed certain Link State Update packets. An OSPF router could use this flaw to crash ospfd on an adjacent router. (CVE-2012-0250) Red Hat would like to thank CERT-FI for reporting CVE-2011-3327, CVE-2011-3323, CVE-2011-3324, CVE-2011-3325, and CVE-2011-3326; and the CERT/CC for reporting CVE-2012-0249 and CVE-2012-0250. CERT-FI acknowledges Riku Hietamäki, Tuomo Untinen and Jukka Taimisto of the Codenomicon CROSS project as the original reporters of CVE-2011-3327, CVE-2011-3323, CVE-2011-3324, CVE-2011-3325, and CVE-2011-3326. The CERT/CC acknowledges Martin Winter at OpenSourceRouting.org as the original reporter of CVE-2012-0249 and CVE-2012-0250. Users of quagga should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the bgpd, ospfd, and ospf6d daemons will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network.

The verification of md5 checksums and GPG signatures is performed automatically for you. All packages are signed by Mandriva for security. The crafted attributes are not propagated by the Internet core, so only explicitly configured direct peers are able to exploit this vulnerability in typical configurations. CVE-2010-1675 The BGP daemon resets BGP sessions when it encounters malformed AS_PATHLIMIT attributes, introducing a distributed BGP session reset vulnerability which disrupts packet forwarding. Such malformed attributes are propagated by the Internet core, and exploitation of this vulnerability is not restricted to directly configured BGP peers. This security update removes AS_PATHLIMIT processing from the BGP implementation, preserving the configuration statements for backwards compatibility. (Standardization of this BGP extension was abandoned long ago.) For the oldstable distribution (lenny), these problems have been fixed in version 0.99.10-1lenny5. For the stable distribution (squeeze), these problems have been fixed in version 0.99.17-2+squeeze2. For the testing distribution (wheezy) and the unstable distribution (sid), these problems will fixed soon.
