Background ========== nfs-utils contains the client and daemon implementations for the NFS protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/nfs-utils < 1.1.3 >= 1.1.3 Description =========== Michele Marcionelli reported that nfs-utils invokes the hosts_ctl() function with the wrong order of arguments, which causes TCP Wrappers to ignore netgroups. Impact ====== A remote attacker could bypass intended access restrictions, i.e. NFS netgroups, and gain access to restricted services. Workaround ========== There is no known workaround at this time. Resolution ========== All nfs-utils users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/nfs-utils-1.1.3" References ========== [ 1 ] CVE-2008-4552 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4552 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200903-06.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
