Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D libxml2 is a library to manipulate XML files. 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 < 2.7.3-r2 >=3D 2.7.3-r2 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D The following vulnerabilities were reported after a test with the Codenomicon XML fuzzing framework: * Two use-after-free vulnerabilities are possible when parsing a XML file with Notation or Enumeration attribute types (CVE-2009-2416). * A stack consumption vulnerability can be triggered via a large depth of element declarations in a DTD, related to a function recursion (CVE-2009-2414). Impact =3D=3D=3D=3D=3D=3D A remote attacker could entice a user or automated system to open a specially crafted XML document with an application using libxml2 resulting in a Denial of Service condition. 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/libxml2-2.7.3-r2" NOTE: This is a legacy GLSA. Updates for all affected architectures are available since August 30, 2009. It is likely that your system is already no longer affected by this issue.
