Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D libxml2 is the XML C parser and toolkit developed for the Gnome project. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libxml2 < 2.9.1-r4 >=3D 2.9.1-r4 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D A vulnerability in the xmlParserHandlePEReference() function of parser.c, when expanding entity references, can be exploited to consume large amounts of memory and cause a crash or hang. Impact =3D=3D=3D=3D=3D=3D A remote attacker may be able to cause Denial of Service via a specially crafted XML file containing malicious attributes. Workaround =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D There is no known workaround at this time. Resolution =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D All libxml2 users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Ddev-libs/libxml2-2.9.1-r4" References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] CVE-2014-0191 http://nvd.nist.gov/nvd.cfm?cvename=3DCVE-2014-0191 Availability =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201409-08.xml Concerns? =3D=3D=3D=3D=3D=3D=3D=3D=3D Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
