Background ========== Samba is a freely available SMB/CIFS implementation which allows seamless interoperability of file and print services to other SMB/CIFS clients. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/samba < 3.0.22-r3 >= 3.0.22-r3 Description =========== During an internal audit the Samba team discovered that a flaw in the way Samba stores share connection requests could lead to a Denial of Service. Impact ====== By sending a large amount of share connection requests to a vulnerable Samba server, an attacker could cause a Denial of Service due to memory consumption. Workaround ========== There is no known workaround at this time. Resolution ========== All Samba users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.22-r3" References ========== [ 1 ] CVE-2006-3403 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3403 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200607-10.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.
