An input validation error in the DirectShow architecture may allow a buffer overflow to occur in applications or components that use DirectShow. If a remote, unauthenticated attacker supplies an application or component that uses DirectShow with a specially crafted media file, that attacker may be able to trigger the buffer overflow and, consequently, execute arbitrary code. For more information, including a list of affected software, please see MS05-050.","impact":"By convincing a user to open a specially crafted media file with an application that uses DirectShow, an attacker may be able to execute arbitrary code with the privileges of the user.","resolution":"Apply an update \nMicrosoft has addressed this issue in Microsoft Security Bulletin MS05-050.","workarounds":"Do not accept media files from untrusted sources By only accessing media files, such as *.avi files, from trusted or known sources, the chances of exploitation are reduced.","sysaffected":"","thanks":"This vulnerability was reported by in Microsoft Security Bulletin \nMS05-050 Microsoft credits \neEye Digital Security\n for reporting this vulnerability.","author":"This document was written by Jeff Gennari.","public":["http://www.microsoft.com/technet/security/Bulletin/MS05-050.mspx","http://eeye.com/html/research/advisories/AD20051011a.html"],"cveids":["CVE-2005-2128"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2005-10-11T18:20:43Z","publicdate":"2005-10-11T00:00:00Z","datefirstpublished":"2005-10-11T19:26:43Z","dateupdated":"2005-10-14T17:37:42Z","revision":29,"vrda_d1_directreport":"","vrda_d1_population":"","vrda_d1_impact":"","cam_widelyknown":"15","cam_exploitation":"0","cam_internetinfrastructure":"3","cam_population":"20","cam_impact":"18","cam_easeofexploitation":"11","cam_attackeraccessrequired":"11","cam_scorecurrent":"14.7015","cam_scorecurrentwidelyknown":"18.78525","cam_scorecurrentwidelyknownexploited":"35.12025","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":14.7015,"vulnote":null}
