{"vuid":"VU#596848","idnumber":"596848","name":"gzip contains an infinite loop vulnerability in its LZH handling","keywords":["Infinite loop","(gzip-lzh-infinite-loop.Z)","apple-2006-007"],"overview":"The gzip program contains a infinite loop vulnerability that may allow an attacker to create a denial-of-service condition.","clean_desc":"The gzip program is used to compress and decompress archived files. A infinite loop vulnerability exists in the way gzip handles certain files. 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 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-2006-4338"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2006-09-08T21:24:28Z","publicdate":"2006-06-19T00:00:00Z","datefirstpublished":"2006-09-19T20:42:35Z","dateupdated":"2011-07-22T12:45:56Z","revision":39,"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":"2","cam_easeofexploitation":"10","cam_attackeraccessrequired":"2","cam_scorecurrent":"0.3135","cam_scorecurrentwidelyknown":"0.38475","cam_scorecurrentwidelyknownexploited":"0.627","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":0.3135,"vulnote":null}
