"Rauli Kaksonen, Tero Rontti and Jukka Taimisto discovered several
vulnerabilities in libxml, a library for parsing and handling XML data
files, which can lead to denial of service conditions or possibly
arbitrary code execution in the application using the library. The
Common Vulnerabilities and Exposures project identifies the following
problems :

  - CVE-2009-2416
    An XML document with specially crafted Notation or
    Enumeration attribute types in a DTD definition leads to
    the use of a pointers to memory areas which have already
    been freed.

  - CVE-2009-2414
    Missing checks for the depth of ELEMENT DTD definitions
    when parsing child content can lead to extensive
    stack-growth due to a function recursion which can be
    triggered via a crafted XML document."
