Vulnerability Description

The remote Ubuntu host is missing one or more security-related patches. It is therefore likely to be vulnerable to the following:

  • It was discovered that libxml2 did not correctly handle root XML document element DTD definitions. If a user were tricked into processing a specially crafted XML document, a remote attacker could cause the application linked against libxml2 to crash, leading to a denial of service. (CVE-2009-2414)
  • It was discovered that libxml2 did not correctly parse Notation and Enumeration attribute types. If a user were tricked into processing a specially crafted XML document, a remote attacker could cause the application linked against libxml2 to crash, leading to a denial of service. (CVE-2009-2416)
  • USN-644-1 fixed a vulnerability in libxml2. This advisory provides the corresponding update for Ubuntu 9.04.
  • It was discovered that libxml2 did not correctly handle long entity names. If a user were tricked into processing a specially crafted XML document, a remote attacker could execute arbitrary code with user privileges or cause the application linked against libxml2 to crash, leading to a denial of service. (CVE-2008-3529).
