The driver for the Linksys WRT350N Wi-Fi access point with firmware 2.00.17 on the Atheros AR5416-AC1E chipset does not properly parse the Atheros vendor-specific information element in an association request, which allows remote authenticated users to cause a denial of service (device reboot or hang) or possibly execute arbitrary code via an Atheros information element with an invalid length, as demonstrated by an element that is too long. Atheros AR5416-AC1E On chipset Linksys WRT350N Wi-Fi The access point driver is responsible for the association request. Atheros Communications AR5416-AC1E is prone to a denial-of-service vulnerability because it fails to perform adequate boundary checks on user-supplied data. Attackers can exploit this issue to crash the affected device that uses the chipset, denying service to legitimate users. Given the nature of this issue, attackers may also be able to run arbitrary code, but this has not been confirmed. Atheros AR5416-AC1E included in Linksys WRT35ON wireless router running firmware 2.00.17 is vulnerable; other devices running different firmware may also be affected. Linksys WRT350N is a popular wireless broadband router. Cause a denial of service or execute arbitrary commands. This information element is used by wireless devices to advertise Atheros specific capabilities. This can be achieved only after a successful 802.11 authentication (in "Open" or "Shared" mode according to the configuration of the wireless access point). This security vulnerability was reported to Linksys, updated firmwares should be available on their web site. Any other wireless device relying on this vulnerable wireless driver is likely to be vulnerable.

The Marvell driver for the Netgear WN802T Wi-Fi access point with firmware 1.3.16 on the Marvell 88W8361P-BEM1 chipset does not properly parse EAPoL-Key packets, which allows remote authenticated users to cause a denial of service (device reboot or hang) or possibly execute arbitrary code via a malformed EAPoL-Key packet with a crafted "advertised length.". The NETGEAR WN802T wireless access point is prone to a denial-of-service vulnerability because it fails to adequately handle long key lengths in EAPoL packets. Successful exploits will deny service to legitimate users. Given the nature of this issue, remote code execution may be possible, but this has not been confirmed. NETGEAR WN802T firmware 1.3.16 with the MARVELL 88W8361P-BEM1 chipset is vulnerable. Other devices running this Marvell chipset may also be affected. This packet is used for unicast/multicast key derivation (which are called 4-way handshake and group key handshake) of any secure wireless connection (WPA-PSK, WPA2-PSK, WPA-EAP, WPA2-EAP). This can be achieved only after a successful 802.11 authentication (in "Open" mode according to the configuration of the wireless access point) and a successful 802.11 association with appropriate security parameters (e.g. WPA w/ TKIP unicast, TKIP multicast) which depends on the configuration of the wireless access point. This security vulnerability was reported to Netgear, updated firmwares should be available on their web site. Any other wireless device relying on this vulnerable wireless driver is likely to be vulnerable.

The Marvell driver for the Netgear WN802T Wi-Fi access point with firmware 1.3.16 on the Marvell 88W8361P-BEM1 chipset does not properly parse the SSID information element in an association request, which allows remote authenticated users to cause a denial of service (device reboot or hang) or possibly execute arbitrary code via a "Null SSID.". The NETGEAR WN802T wireless access point is prone to a denial-of-service vulnerability because it fails to adequately verify user-supplied input. Attackers can exploit this issue to hang or reboot the device, denying service to legitimate users. The NETGEAR WN802T wireless access point running firmware 1.3.16 on the Marvell 88W8361P-BEM1 chipset is vulnerable. Other devices running this Marvell chipset may also be affected. Most information elements are used by the wireless access point and clients to advertise their capabilities (regarding rates, network name, cryptographic capabilities...). More precisely, the SSID is used by the access point to validate that the wireless client intends to connect to the appropriate SSID. Assigned CVE: ------------- * CVE-2008-1197 Details: -------- * The bug can be triggered by a malicious association request to the wireless access point with a Null SSID.

Because this affects CSAuth all authentication requests via RADIUS or TACACS+ will be affected during exploitation of this vulnerability. Cisco ACS installations that are configured with AAA Clients to authenticate using TACACS+ only are not affected by this vulnerability. The RADIUS shared secret and a valid known Network Access Server (NAS) IP address must be known to carry out this exploit. The Cisco PSIRT team greatly appreciates the opportunity to work with researchers on security vulnerabilities, and we welcome the opportunity to review and assist in product reports. We thank Laurent Butti and Gabriel Campana of Orange Labs / France Telecom Group for reporting this vulnerability to Cisco PSIRT. Software patches are available for customers with support contracts and should be obtained through their regular support channels. The upgrade to fixed software is not a free upgrade. See Software Versions and Fixes section within this advisory for further information on obtaining fixed software. It is the integration and control layer for managing enterprise network users, administrators, and the resources of the network infrastructure. Described in RFC2865, RADIUS is a distributed client/server system that secures networks against unauthorized access. In the Cisco implementation, RADIUS clients run on Cisco devices and send authentication requests to a central RADIUS server (Cisco Secure ACS) that contains all user authentication and network service access information. Described in RFC3748, EAP is an authentication framework that supports multiple authentication methods. Typically, EAP runs directly over data link layers, such as Point-to-Point Protocol (PPP) or IEEE 802, without requiring IP. A specially crafted RADIUS EAP Message Attribute packet will crash the CSRadius and CSAuth services. An error message will be indicated in the Windows event viewer - System Log indicating "The CSAuth service terminated unexpectedly" and "The CSRadius service terminated unexpectedly". In the Cisco ACS Reports and Activity tab, under ACS Service Monitoring, the logs will indicate CSAuth is not running and attempts to restart. The CSRadius service handles communication between the service for authentication and authorization (CSAuth service) and the access device requesting the authentication and authorization services for RADIUS. In many cases continued exploitation will prevent network access to devices which first require authentication or authorization via the AAA Server. Software Versions and Fixes +-------------------------- When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release.

SSL VPN Memory Leak Vulnerability and URI Processing Error Vulnerability in SSL VPNs A crafted SSL or HTTP packet may cause a denial of service condition on a Cisco ASA device that is configured to terminate clientless VPN connections. A successful attack may result in a reload of the device. Cisco ASA devices that run versions 7.2, 8.0, or 8.1 with clientless SSL VPNs enabled may be affected by this vulnerability. Devices that run software versions 7.0 and 7.1 are not affected by this vulnerability. Clientless VPN, SSL VPN Client, and AnyConnect connections are enabled via the webvpn command. For example, the following configuration shows a Cisco ASA with Clientless VPNs configured and enabled. In this case the ASA will listen for VPN connections on the default port, TCP port 443: http server enable ! webvpn enable outside Note that with this particular configuration, the device is vulnerable to attacks coming from the outside interface due to the enable outside command within the webvpn group configuration. These vulnerabilities are documented in Cisco Bug ID CSCso66472 and CSCsq19369. They have been assigned Common Vulnerabilities and Exposures (CVE) identifiers CVE-2008-2734 and CVE-2008-2735. Potential Information Disclosure in Clientless VPNs On Cisco ASA devices configured to terminate clientless VPN connections, an attacker may be able to discover potentially sensitive information such as usernames and passwords. This attack requires an attacker to convince a user to visit a rogue web server, reply to an e-mail, or interact with a service to successfully exploit the vulnerability. Cisco ASA devices running software versions 8.0 or 8.1 with clientless VPNs enabled may be affected by this vulnerability. Clientless SSL VPN connections are enabled via the webvpn command. For example, the following configuration shows a Cisco ASA device with Clientless VPNs configured and enabled. In this case the Cisco ASA device will listen for VPN connections on the default port, TCP port 443: http server enable ! webvpn enable outside Note that with this particular configuration, the device is vulnerable to attacks coming from the outside interface due to the enable outside command within the webvpn group configuration.

The problem is Bug ID : CSCso69942 It is a problem.Service operation disrupted by a third party (DoS) There is a possibility of being put into a state. Cisco PIX and ASA are prone to multiple denial-of-service vulnerabilities and an information-disclosure vulnerability. An attacker can exploit these issues to obtain sensitive information or cause the affected devices to reload. PIX is a firewall device that provides policy enforcement, multi-vector attack protection and secure connection services for users and applications; Adaptive Security Appliance (ASA) is a modular platform that provides security and VPN services. This security advisory outlines details of the following vulnerabilities: * Erroneous SIP Processing Vulnerabilities * IPSec Client Authentication Processing Vulnerability * SSL VPN Memory Leak Vulnerability * URI Processing Error Vulnerability in SSL VPNs * Potential Information Disclosure in Clientless VPNs Note: These vulnerabilities are independent of each other. A device may be affected by one vulnerability and not affected by another. Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate some of these vulnerabilities are available. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20080903-asa.shtml Affected Products ================= The following paragraphs describe the affected Cisco ASA and Cisco PIX software versions: Vulnerable Products +------------------ The following sections provide details on the versions of Cisco ASA that are affected by each vulnerability. The show version command-line interface (CLI) command can be used to determine if a vulnerable version of the Cisco PIX or Cisco ASA software is running. The following example shows a Cisco ASA device that runs software release 8.0(2): ASA# show version Cisco Adaptive Security Appliance Software Version 8.0(2) Device Manager Version 6.0(1) [...] Customers who use the Cisco Adaptive Security Device Manager (ASDM) to manage their devices can find their software version displayed in a table in the login window or in the upper left corner of the ASDM window. Erroneous SIP Processing Vulnerabilities Cisco PIX and Cisco ASA devices configured for SIP inspection are vulnerable to multiple processing errors that may result in denial of service attacks. Potential Information Disclosure in Clientless VPNs Cisco ASA devices that terminate clientless remote access VPN connections are vulnerable to potential information disclosure if the device is running affected 8.0 or 8.1 software versions. Products Confirmed Not Vulnerable +-------------------------------- The Cisco Firewall Services Module (FWSM) is not affected by any of these vulnerabilities. Cisco PIX security appliances running software versions 6.x are not vulnerable. IOS, IOS XR, and Cisco Unified Boarder Elements (CUBE) are not vulnerable to these issues. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The following sections provide details to help determine if a device may be affected by any of the vulnerabilities. Erroneous SIP Processing Vulnerabilities Cisco PIX and Cisco ASA devices configured for SIP inspection are vulnerable to multiple processing errors that may result in denial of service attacks. A successful attack may result in a reload of the device. SIP inspection is enabled with the inspect sip command. To determine whether the Cisco PIX or Cisco ASA security appliance is configured to support inspection of sip packets, log in to the device and issue the CLI command show service-policy | include sip. If the output contains the text Inspect: sip and some statistics, then the device has a vulnerable configuration. The following example shows a vulnerable Cisco ASA Security Appliance: asa#show service-policy | include sip Inspect: sip, packet 0, drop 0, reset-drop 0 asa# These vulnerability is documented in the following Cisco Bug IDs and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-2732. Devices that run software versions 7.0 or 7.1 are not affected by this vulnerability. A successful attack may result in a reload of the device. Remote access VPN connections will have Internet Security Association and Key Management Protocol (ISAKMP) enabled on an interface with the crypto command, such as: crypto isakmp enable outside. This vulnerability is documented in Cisco Bug ID CSCso69942 and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-2733. A successful attack may result in a reload of the device. Cisco ASA devices that run versions 7.2, 8.0, or 8.1 with clientless SSL VPNs enabled may be affected by this vulnerability. Devices that run software versions 7.0 and 7.1 are not affected by this vulnerability. Clientless VPN, SSL VPN Client, and AnyConnect connections are enabled via the webvpn command. For example, the following configuration shows a Cisco ASA with Clientless VPNs configured and enabled. In this case the ASA will listen for VPN connections on the default port, TCP port 443: http server enable ! webvpn enable outside Note that with this particular configuration, the device is vulnerable to attacks coming from the outside interface due to the enable outside command within the webvpn group configuration. These vulnerabilities are documented in Cisco Bug ID CSCso66472 and CSCsq19369. They have been assigned Common Vulnerabilities and Exposures (CVE) identifiers CVE-2008-2734 and CVE-2008-2735. Potential Information Disclosure in Clientless VPNs On Cisco ASA devices configured to terminate clientless VPN connections, an attacker may be able to discover potentially sensitive information such as usernames and passwords. This attack requires an attacker to convince a user to visit a rogue web server, reply to an e-mail, or interact with a service to successfully exploit the vulnerability. Cisco ASA devices running software versions 8.0 or 8.1 with clientless VPNs enabled may be affected by this vulnerability. Clientless SSL VPN connections are enabled via the webvpn command. For example, the following configuration shows a Cisco ASA device with Clientless VPNs configured and enabled. In this case the Cisco ASA device will listen for VPN connections on the default port, TCP port 443: http server enable ! webvpn enable outside Note that with this particular configuration, the device is vulnerable to attacks coming from the outside interface due to the enable outside command within the webvpn group configuration. This vulnerability is documented in Cisco Bug ID CSCsq45636 and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-2736.

This vulnerability is documented in Cisco Bug ID CSCso69942 and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-2733. A successful attack may result in a reload of the device. Devices that run software versions 7.0 and 7.1 are not affected by this vulnerability. Clientless VPN, SSL VPN Client, and AnyConnect connections are enabled via the webvpn command. For example, the following configuration shows a Cisco ASA with Clientless VPNs configured and enabled. In this case the ASA will listen for VPN connections on the default port, TCP port 443: http server enable ! webvpn enable outside Note that with this particular configuration, the device is vulnerable to attacks coming from the outside interface due to the enable outside command within the webvpn group configuration. These vulnerabilities are documented in Cisco Bug ID CSCso66472 and CSCsq19369. They have been assigned Common Vulnerabilities and Exposures (CVE) identifiers CVE-2008-2734 and CVE-2008-2735. This attack requires an attacker to convince a user to visit a rogue web server, reply to an e-mail, or interact with a service to successfully exploit the vulnerability. Cisco ASA devices running software versions 8.0 or 8.1 with clientless VPNs enabled may be affected by this vulnerability. Clientless SSL VPN connections are enabled via the webvpn command. For example, the following configuration shows a Cisco ASA device with Clientless VPNs configured and enabled. In this case the Cisco ASA device will listen for VPN connections on the default port, TCP port 443: http server enable ! webvpn enable outside Note that with this particular configuration, the device is vulnerable to attacks coming from the outside interface due to the enable outside command within the webvpn group configuration.

sys/netinet6/icmp6.c in the kernel in FreeBSD 6.3 through 7.1, NetBSD 3.0 through 4.0, and possibly other operating systems does not properly check the proposed new MTU in an ICMPv6 Packet Too Big Message, which allows remote attackers to cause a denial of service (panic) via a crafted Packet Too Big Message. A vulnerability in some implementations of the IPv6 Neighbor Discovery Protocol may allow a nearby attacker to intercept traffic or cause congested links to become overloaded. FreeBSD is prone to a remote denial-of-service vulnerability. Remote attackers can exploit this issue to cause the kernel's TCP stack to panic, denying service to legitimate users. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ============================================================================= FreeBSD-SA-08:09.icmp6 Security Advisory The FreeBSD Project Topic: Remote kernel panics on IPv6 connections Category: core Module: sys_netinet6 Announced: 2008-09-03 Credits: Tom Parker, Bjoern A. Zeeb Affects: All supported versions of FreeBSD. Corrected: 2008-09-03 19:09:47 UTC (RELENG_7, 7.1-PRERELEASE) 2008-09-03 19:09:47 UTC (RELENG_7_0, 7.0-RELEASE-p4) 2008-09-03 19:09:47 UTC (RELENG_6, 6.4-PRERELEASE) 2008-09-03 19:09:47 UTC (RELENG_6_3, 6.3-RELEASE-p4) CVE Name: CVE-2008-3530 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:http://security.FreeBSD.org/>. I. Background IPv6 nodes use ICMPv6 amongst other things to report errors encountered while processing packets. The 'Packet Too Big Message' is sent in case a node cannot forward a packet because the size of the packet is larger than the MTU of next-hop link. II. III. Workaround Systems without INET6 / IPv6 support are not vulnerable and neither are systems which do not listen on any IPv6 TCP sockets and have no active IPv6 connections. Filter ICMPv6 'Packet Too Big Messages' using a firewall, but this will at the same time break PMTU support for IPv6 connections. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 6-STABLE or 7-STABLE, or to the RELENG_6_3 or RELENG_7_0 security branch dated after the correction date. 2) To patch your present system: The following patches have been verified to apply to FreeBSD 6.3 and FreeBSD 7.0 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch http://security.FreeBSD.org/patches/SA-08:09/icmp6.patch # fetch http://security.FreeBSD.org/patches/SA-08:09/icmp6.patch.asc b) Apply the patch. # cd /usr/src # patch < /path/to/patch c) Recompile your kernel as described in <URL:http://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the system. VI. Correction details The following list contains the revision numbers of each file that was corrected in FreeBSD.
