A local user may be able to obtain root access. According to SSH Communications Security: AFFECTED PRODUCTS\n* SSH Tectia client and SSH Tectia Server 5.0, 5.1, 5.2 and 5.3 up to 5.2.3 and 5.3.5 (all Linux and Unix) NOT AFFECTED PRODUCTS\n* 4.x or older SSH Tectia client/server solution versions are NOT affected. * Any version of SSH Tectia client/server solution for IBM mainframes is NOT affected. * Any version of SSH Tectia client/server solution for Windows is NOT affected.","impact":"A local user may be able to obtain root access.","resolution":"Apply an update\nThis issue is addressed in SSH Tectia Client/Server solution 5.2.4 and 5.3.6.","workarounds":"Remove ssh-signer This vulnerability can be mitigated by removing the ssh-signer binary, which is located in /opt/tectia/libexec/. Note that this will disable host-based authentication of the SSH Tectia Client. This will have no adverse effect on SSH Tectia Server.","sysaffected":"","thanks":"Thanks to Tuomas Siren for reporting this vulnerability.","author":"This document was written by Will Dormann.","public":["http://www.ssh.com/products/client-server/","http://xforce.iss.net/xforce/xfdb/39569","http://www.securitytracker.com/id?1019167","http://secunia.com/advisories/28247/","http://www.securityfocus.com/bid/27191"],"cveids":["CVE-2007-5616"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2008-01-07T15:02:56Z","publicdate":"2008-01-08T00:00:00Z","datefirstpublished":"2008-01-08T14:57:37Z","dateupdated":"2008-01-14T14:53:12Z","revision":6,"vrda_d1_directreport":"1","vrda_d1_population":"2","vrda_d1_impact":"2","cam_widelyknown":"3","cam_exploitation":"0","cam_internetinfrastructure":"9","cam_population":"5","cam_impact":"20","cam_easeofexploitation":"10","cam_attackeraccessrequired":"10","cam_scorecurrent":"2.25","cam_scorecurrentwidelyknown":"5.4375","cam_scorecurrentwidelyknownexploited":"9.1875","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":2.25,"vulnote":null}
