{"vuid":"VU#682110","idnumber":"682110","name":"Multiple Symantec firewall products fail to properly process DNS response packets","keywords":["Symantec","firewall products","UDP","Domain Name Service","DNS","port 53/udp","SYMDNS.SYS","AD20040512B","SYM04-008"],"overview":"There is a vulnerability in multiple Symantec firewall products in which attempts to process a specially crafted Domain Name Service (DNS) response packet could allow an unauthenticated, remote attacker to cause a denial of service condition.","clean_desc":"Symantec offers a suite of corporate and consumer security products including a firewall application. The firewall application includes a SYMDNS.SYS driver, which is responsible for validating DNS and NetBIOS Name Service (NBNS) responses. There is a vulnerability in the routine responsible for processing incoming DNS responses. By supplying a DNS packet containing a specially crafted compressed name pointer, an attacker could cause the kernel to enter an infinite loop on the vulnerable system. According to the Symantec Advisory, the following products are affected: Consumer: Symantec Norton Internet Security and Professional 2002, 2003, 2004\nSymantec Norton Personal Firewall 2002, 2003, 2004\nSymantec Norton AntiSpam 2004 Corporate: Symantec Client Firewall 5.01, 5.1.1\nSymantec Client Security 1.0, 1.1, 2.0(SCF 7.1)","impact":"An unauthenticated, remote attacker could cause a denial of service condition on the vulnerable system. In order to regain functionality, the system may have to be rebooted.","resolution":"Apply Patch\nSymantec recommends that clients running corporate versions of the affected products apply patches obtained through their appropriate support channels. Use LiveUpdate\nSymantec recommends that clients running consumer versions of the affected products use the LiveUpdate feature to ensure all updates are installed. According to Symantec, this can be done as follows: Open any installed Symantec product\nClick on LiveUpdate in the toolbar\nRun LiveUpdate until Symantec LiveUpdate indicated that all installed Symantec products are up-to-date\nDepending on the application, system may require a reboot to effectively update available fixes","workarounds":"","sysaffected":"","thanks":"This vulnerability was reported by \neEye Digital Security","author":"This document was written by Damon Morda and based on information contained in the eEye Digital Security Advisory.","public":["http://www.eeye.com/html/Research/Advisories/AD20040512B.html","http://securityresponse.symantec.com/avcenter/security/Content/2004.05.12.html","http://secunia.com/advisories/11066/"],"cveids":["CVE-2004-0445"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2004-05-13T12:32:51Z","publicdate":"2004-05-12T00:00:00Z","datefirstpublished":"2004-05-13T17:01:07Z","dateupdated":"2004-05-13T17:27:32Z","revision":9,"vrda_d1_directreport":"","vrda_d1_population":"","vrda_d1_impact":"","cam_widelyknown":"15","cam_exploitation":"0","cam_internetinfrastructure":"10","cam_population":"10","cam_impact":"8","cam_easeofexploitation":"15","cam_attackeraccessrequired":"17","cam_scorecurrent":"9.5625","cam_scorecurrentwidelyknown":"11.475","cam_scorecurrentwidelyknownexploited":"19.125","ipprotocol":"","cvss_accessvector":"","cvss_accesscomplexity":"","cvss_authentication":null,"cvss_confidentialityimpact":"","cvss_integrityimpact":"","cvss_availabilityimpact":"","cvss_exploitablity":null,"cvss_remediationlevel":"","cvss_reportconfidence":"","cvss_collateraldamagepotential":"","cvss_targetdistribution":"","cvss_securityrequirementscr":"","cvss_securityrequirementsir":"","cvss_securityrequirementsar":"","cvss_basescore":"","cvss_basevector":"","cvss_temporalscore":"","cvss_environmentalscore":"","cvss_environmentalvector":"","metric":9.5625,"vulnote":null}
