T-023: Multiple Vulnerabilities in Cisco PIX and Cisco ASA
Multiple vulnerabilities exist in the Cisco ASA 5500 Series Adaptive Security Appliances and Cisco PIX Security Appliances: 1) Windows NT domain authentication bypass; 2) IPv6 Denial of Service; and 3) Crypto Accelerator memory leak. NOTE: These vulnerabilities are independent of each other. A device may be affected by one vulnerability and not affected by another. The risk is MEDIUM. A remote intruder could make a VPN connection to a network without needing to authenticate.
Hi all,
I need this as soon as possible to solve it or at least to find out what is the problem.
I have configured IPSec tunnels with Openswan and Cisco ASA, i have established a connection and the ping was fine, but after some time there is request time out from both sites. I don't have ASA... (0 Replies)
Hi,I want connect my ASA 5510 firewall to a 3750 switch with RIP routing. Unfortunately,I am having issues passing the VPN subnet through rip to the 3750.I don't understand how the routing table is populated on the ASA. Any suggestions? (0 Replies)
Hi,
I am trying to establish vpn between my linux server and cisco asa at client side.
I installed openswan on my cent os.
Linux Server
eth0 - 182.2.29.10
Gateway - 182.2.29.1
eth1 - 192.9.200.75
I have simple IPtables Like
WAN="eth0"
LAN="eth1" (0 Replies)

FILTER BACKENDS(7) Miscellaneous Information Manual FILTER BACKENDS(7)NAME
filter_backends - output drivers for the filtergen packet filter compiler
INTRODUCTION
This document describes the status and feature-set of the currently available filtergen backends.
IPTABLES
Most development is done first against the iptables driver. It supports reject, masquerading, transparent proxying, logging (with text)
and sub-groups, all of which should work fine (though the latter has only recently been fixed).
IPCHAINS
The ipchains driver supports all of the above features, too. Its state model is much weaker though, of course. The forwarding support
should work OK, though it is not possible to support "local"-only packets.
IPFILTER
The ipfilter backend is incomplete. It supports accept, drop, reject and logging, but not masq, transproxy or sub-groups. It should be
easy for someone with knowledge of ipfilter to add support for the other features. Options for OpenBSD "pf" features and syntax would be
nice, too. It has received no testing; I don't even know if the generated filters are syntactically correct.
CISCO
The cisco driver is in roughly the same sort of state as the ipfilter one. Additionally, because of the limitations of IOS ACLs, it sup-
ports only a limited set of features. It cannot support reject or transparent proxying, and may not be able to support masquerading
either. An option for reflexive (stateful) ACLs would be very useful.
I understand that Cisco PIX firewalls use a variant of this syntax -- it would be very nice to support them too.
