Title:	Conectiva Security Advisory CLA-2002:523
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory CLA-2002:523. The util-linux package contains a large variety of system utilities that are necessary for a Linux system to function. Among many features, it includes the chfn utility, a suid root tool used to change user account information. Michal Zalewski found a race condition vulnerability[1] in the way chfn locks files when changing /etc/passwd. In order to sucessfully exploit this vulnerability, some administrator interaction is needed and there are some prerequisites to fulfill. Full details can be found in the Bindview advisory[2]. Having what appears to be a stale /etc/ptmptmp file could be a sign that the vulnerability is being exploited. In that case, the administrator should investigate current users and processes before attemtping to remove this file. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2002-0638 to this issue[3]. Please note that the fixed packages were available in our ftp servers since September 2nd, 2002. Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade' http://www.kb.cert.org/vuls/id/405955 http://razor.bindview.com/publish/advisories/adv_chfn.html http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2002-0638 http://distro.conectiva.com.br/bugzilla/show_bug.cgi?id=6401 http://www.securityspace.com/smysecure/catid.html?in=CLA-2002:523 http://distro.conectiva.com.br/atualizacoes/index.php?id=a&anuncio=002002 Risk factor : High CVSS Score: 6.2
