Insight
It was discovered that libxml2, the GNOME XML library, didn't correctly handle long entity names. This could allow the execution of arbitrary code via a malicious XML file. For the stable distribution (etch), this problem has been fixed in version 2.6.27.dfsg-5. For the unstable distribution (sid), this problem has been fixed in version 2.6.32.dfsg-4. We recommend that you upgrade your libxml2 package.
