Background ========== Mono provides the necessary software to develop and run .NET client and server applications on various platforms. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/mono < 1.2.2.1 >= 1.2.2.1 Description =========== José Ramón Palanco has discovered that the System.Web class in the XSP for the ASP.NET server 1.1 through 2.0 in Mono does not properly validate or sanitize local pathnames which could allow server-side file content disclosure. Impact ====== An attacker could append a space character to a URI and obtain unauthorized access to the source code of server-side files. An attacker could also read credentials by requesting Web.Config%20 from a Mono server. Workaround ========== There is no known workaround at this time. Resolution ========== All Mono users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/mono-1.2.2.1" References ========== [ 1 ] CVE-2006-6104 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6104 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200701-12.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.
