Security vulnerabilities in the libxml2 (see libxml(3)) related to parsing of Element declarations, Notation and Enumeration attribute types, may allow a local or remote unprivileged user who provides a specially crafted XML file to cause a Denial of Service (DoS) via an application crash to the application that is using the libxml2 library. The precise impact will vary depending on the application.

These issues are also described in the following documents:

Title: DSA-1859-1 libxml2 -- several
Description: Rauli Kaksonen, Tero Rontti and Jukka Taimisto discovered several vulnerabilities in libxml2, 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: 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. 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. For the oldstable distribution, this problem has been fixed in version 2.6.27.dfsg-6+etch1. For the stable distribution, this problem has been fixed in version 2.6.32.dfsg-5+lenny1. For the testing and unstable distribution, this problem will be fixed soon. We recommend that you upgrade your libxml2 packages.

Description: 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: 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. 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. For the oldstable distribution, this problem has been fixed in version 1.8.17-14+etch1. The stable, testing and unstable distribution do not contain libxml anymore but libxml2 for which DSA-1859-1 has been released. We recommend that you upgrade your libxml packages.

Description: Updated libxml and libxml2 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3, 4, and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. libxml is a library for parsing and manipulating XML files. A Document Type Definition (DTD) defines the legal syntax (and also which elements can be used) for certain types of files, such as XML files.
