13:44 Dnsupdate from the microsoft conflict with the firewall zonealarm | |
| The company Check Point Software Technologies, producer of the popular firewall ZoneAlarm, reported that many users of the firewall had been completely cut off from the Internet after installing the latest patch in the Microsoft Update. This patch closes a hole associated with a serious vulnerability in the protocol DNS, on which it became known two days ago. A vulnerability in the DNS protocol has been so severe, that lifted her to the ears of all security professionals related to Internet technologies. If not urgently patched DNS-server on the Internet (and they still nepropatcheny), the hypothetical attacker, DNS-changing table can easily redirect the request to any server on any other server (for example, all mail user can be redirected to the attacker's site and from there to the addressee), and is completely transparent to the user. True, over the past couple of days until the attackers but did not have time to react to the discovery of new holes (they are certainly working on it right now). Microsoft is quickly released update KB951748 (MS08-037) for Windows 2000, XP and Server 2003, which amends the system of Windows Domain Name System (DNS). However, if users firewall ZoneAlarm, which in the settings is "high" level of security, install the patch, they have completely lost the opportunity to connect to the Internet. Until the problem is not solved, Check Point recommends users remove the patch from your system, download the new version of the firewall or reduce the level of security on the firewall to "medium". | |
