{"vuid":"VU#897540","idnumber":"897540","name":"Mozilla products VCard attachment buffer overflow","keywords":["Mozilla","VCard attachment","base64","heap buffer overwrite","integer underflow","firefox_1505"],"overview":"Mozilla products fail to properly handle malformed VCard attachments, which allows a buffer overflow to occur. This vulnerability may allow a remote attacker to execute arbitrary code on a vulnerable system.","clean_desc":"According to Mozilla Foundation Security Advisory 2006-49: A VCard attachment with a malformed base64 field (such as a photo) can trigger a heap buffer overwrite. These have proven exploitable in the past, though in this case the overwrite is accompanied by an integer underflow that would attempt to copy more data than the typical machine has, leading to a crash. For more information and a complete list of affected products, refer to Mozilla Foundation Security Advisory 2006-49.","impact":"A remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. The attacker could also cause the vulnerable application to crash.","resolution":"Apply an update \nThis vulnerability is addressed in Thunderbird 1.5.0.5 and SeaMonkey 1.0.3 according to the Mozilla Foundation Security Update 2006-49.","workarounds":"Mozilla Foundation Security Advisory 2006-49, suggests the following workarounds: Turn off the inline display of attachments. Do not click on or open VCard attachments.","sysaffected":"","thanks":"This vulnerability was reported in Mozilla Foundation Security Advisory \n2006-49","author":"This document was written by Jeff Gennari.","public":["http://www.mozilla.org/security/announce/2006/mfsa2006-49.html","https://bugzilla.mozilla.org/show_bug.cgi?id=339740","http://www.securityfocus.com/bid/19181"],"cveids":["CVE-2006-3804"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2006-07-27T15:38:00Z","publicdate":"2006-07-25T00:00:00Z","datefirstpublished":"2006-07-27T16:07:55Z","dateupdated":"2007-02-09T14:03:11Z","revision":19,"vrda_d1_directreport":"0","vrda_d1_population":"3","vrda_d1_impact":"3","cam_widelyknown":"8","cam_exploitation":"0","cam_internetinfrastructure":"15","cam_population":"15","cam_impact":"19","cam_easeofexploitation":"5","cam_attackeraccessrequired":"10","cam_scorecurrent":"6.1453125","cam_scorecurrentwidelyknown":"9.3515625","cam_scorecurrentwidelyknownexploited":"14.6953125","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":6.1453125,"vulnote":null}
