Background ========== XStream is a simple library to serialize objects to XML and back again. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-java/xstream < 1.4.8-r1 >= 1.4.8-r1 Description =========== It was found that XStream would deserialize arbitrary user-supplied XML content, thus representing objects of any type. Impact ====== A remote attacker could pass a specially crafted XML document to XStream, possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All XStream users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-java/xstream-1.4.8-r1" References ========== [ 1 ] CVE-2013-7285 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-7285 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201612-35 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.
