{"vuid":"VU#794752","idnumber":"794752","name":"Apple iChat AIM URI handler format string vulnerability","keywords":["Apple","iChat","format string","AIM","URI scheme","aim://","cert-seccode:FIO30-C","Apple-2007-002"],"overview":"Apple iChat contains a format string vulnerability. This vulnerability may allow a remote, unauthenticated attacker to execute arbitary code.","clean_desc":"The Apple iChat AIM URI handler fails to properly sanitize user-controlled data that is supplied to a formatted output function. This may allow a format string vulnerability to occur. Depending on the user's browser, an attacker may be able to exploit this vulnerability by persuading a user to access a specially crafted web page. Some web browsers, such as Safari, automatically launch iChat to handle certain types of URIs. So, if a Safari user accesses a web page containing a specially crafted URI, iChat will be launched to process that URI. This may trigger the vulnerability.","impact":"A remote, unauthenticated attacker may be able to execute arbitrary code.","resolution":"Apply an update\nApple has addressed this issue with Apple Security Update 2007-002.","workarounds":"","sysaffected":"","thanks":"This vulnerability was publicly disclosed as part of the \nMonth of Apple Bugs\n project.","author":"This document was written by Jeff Gennari.","public":["http://projects.info-pull.com/moab/MOAB-20-01-2007.html","http://docs.info.apple.com/article.html?artnum=305102","http://secunia.com/advisories/24198/","http://securitytracker.com/alerts/2007/Feb/1017661.html","http://www.securityfocus.com/bid/22146"],"cveids":["CVE-2007-0021"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2007-01-22T20:16:53Z","publicdate":"2007-01-20T00:00:00Z","datefirstpublished":"2007-02-16T15:57:04Z","dateupdated":"2007-03-05T17:01:51Z","revision":25,"vrda_d1_directreport":"0","vrda_d1_population":"2","vrda_d1_impact":"2","cam_widelyknown":"8","cam_exploitation":"0","cam_internetinfrastructure":"3","cam_population":"13","cam_impact":"17","cam_easeofexploitation":"13","cam_attackeraccessrequired":"20","cam_scorecurrent":"11.851125","cam_scorecurrentwidelyknown":"24.779625","cam_scorecurrentwidelyknownexploited":"46.327125","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":11.851125,"vulnote":null}
