{"vuid":"VU#381508","idnumber":"381508","name":"gzip contains an array out-of-bounds vulnerability in make_table()","keywords":["gzip","stack modification","stack buffer","LZH decompression support","apple-2006-007"],"overview":"The gzip program contains a stack modification vulnerability that may allow an attacker to execute arbitrary code, or create a denial-of-service condition..","clean_desc":"The gzip program is used to compress and decompress archived files. A stack modification vulnerability exists in gzip. An attacker may be able to exploit this vulnerability by convincing a user to open a specially crafted gzip file. Note that the attacker could either convince a user to open a malicious gzip file, or save the file in a place where another program would call gzip to decompress the archive.","impact":"A remote, unauthenticated attacker may be able to execute arbitrary code, or create a denial-of-service condition..","resolution":"Upgrade\nThis issue has been addressed in gzip 1.3.6. See the systems affected section of this document for information about specific vendors.","workarounds":"Workarounds\nUntil updates can be applied, the following workarounds may mitigate the impact of this vulnerability: Do not decompress gzip files that are received from unknown sources. Do not execute gzip with system-level privileges. Some automated processes may rely on gzip to complete their tasks. When possible, disable such programs or do not allow them to execute gzip with root privileges.","sysaffected":"","thanks":"Thanks to Tavis Ormandy, Google Security Team for reporting this issue.","author":"This document was written by Ryan Giobbi.","public":["http://www.gzip.org/","http://www.auscert.org.au/7179"],"cveids":["CVE-2006-4335"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2006-09-05T20:54:30Z","publicdate":"2006-06-19T00:00:00Z","datefirstpublished":"2006-09-19T20:35:00Z","dateupdated":"2011-07-22T12:54:56Z","revision":56,"vrda_d1_directreport":"1","vrda_d1_population":"4","vrda_d1_impact":"3","cam_widelyknown":"15","cam_exploitation":"3","cam_internetinfrastructure":"4","cam_population":"19","cam_impact":"10","cam_easeofexploitation":"10","cam_attackeraccessrequired":"2","cam_scorecurrent":"1.5675","cam_scorecurrentwidelyknown":"1.92375","cam_scorecurrentwidelyknownexploited":"3.135","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":1.5675,"vulnote":null}
