{"vuid":"VU#302836","idnumber":"302836","name":"Microsoft Excel fails to properly process a malformed Column record","keywords":["Microsoft","Excel","remote code execution","Column record","ms07-jan"],"overview":"Microsoft Excel contains a memory corruption vulnerability that could enable an attacker to exectue arbitrary code and gain complete control of the vulnerable system.","clean_desc":"Microsoft Excel fails to properly handle malformed Column records. When an Excel file is opened, Excel does not properly perform data validation on the Column record. An attacker could send a specially crafted Column record in the Excel file that, when opened, could corrupt system memory allowing the attacker to execute arbitrary code. The attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.","impact":"An attacker could gain complete control of the affected system and execute arbitrary code.","resolution":"Microsoft addresses this vulnerability with the updates listed in Microsoft Security Bulletin MS07-002. Note that Microsoft has re-released the updates in Microsoft Security Bulletin MS07-002 for Excel 2000. See the Microsoft Security Response Center blog for more information.","workarounds":"Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.","sysaffected":"","thanks":"Thanks to Greg MacManus of iDefense Labs for reporting this vulnerability.","author":"This document was written by Joseph Pruszynski.","public":["http://www.microsoft.com/technet/security/Bulletin/MS07-002.mspx","http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=460","http://www.securityfocus.com/bid/21925","http://securitytracker.com/alerts/2007/Jan/1017487.html","http://blogs.technet.com/msrc/archive/2007/01/18/re-release-of-ms07-002-for-excel-2000.aspx"],"cveids":["CVE-2007-0030"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2007-01-09T18:51:12Z","publicdate":"2007-01-09T00:00:00Z","datefirstpublished":"2007-01-09T21:18:00Z","dateupdated":"2007-01-23T17:17:58Z","revision":15,"vrda_d1_directreport":"0","vrda_d1_population":"3","vrda_d1_impact":"3","cam_widelyknown":"15","cam_exploitation":"15","cam_internetinfrastructure":"5","cam_population":"20","cam_impact":"17","cam_easeofexploitation":"15","cam_attackeraccessrequired":"18","cam_scorecurrent":"60.24375","cam_scorecurrentwidelyknown":"68.85","cam_scorecurrentwidelyknownexploited":"77.45625","ipprotocol":"","cvss_accessvector":"--","cvss_accesscomplexity":"--","cvss_authentication":null,"cvss_confidentialityimpact":"--","cvss_integrityimpact":"--","cvss_availabilityimpact":"--","cvss_exploitablity":null,"cvss_remediationlevel":"ND","cvss_reportconfidence":"ND","cvss_collateraldamagepotential":"ND","cvss_targetdistribution":"ND","cvss_securityrequirementscr":"ND","cvss_securityrequirementsir":"ND","cvss_securityrequirementsar":"ND","cvss_basescore":"0","cvss_basevector":"AV:--/AC:--/Au:--/C:--/I:--/A:--","cvss_temporalscore":"0","cvss_environmentalscore":"0","cvss_environmentalvector":"CDP:ND/TD:ND/CR:ND/IR:ND/AR:ND","metric":60.24375,"vulnote":null}
