Title:	Debian: Security Advisory (DLA-691-1)
Summary:	The remote host is missing an update for the Debian 'libxml2' package(s) announced via the DLA-691-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'libxml2' package(s) announced via the DLA-691-1 advisory. Vulnerability Insight: CVE-2016-4658 Namespace nodes must be copied to avoid use-after-free errors. But they don't necessarily have a physical representation in a document, so simply disallow them in XPointer ranges. CVE-2016-5131 The old code would invoke the broken xmlXPtrRangeToFunction. range-to isn't really a function but a special kind of location step. Remove this function and always handle range-to in the XPath code. The old xmlXPtrRangeToFunction could also be abused to trigger a use-after-free error with the potential for remote code execution. For Debian 7 Wheezy, these problems have been fixed in version 2.8.0+dfsg1-7+wheezy7. We recommend that you upgrade your libxml2 packages.

Solution: Please install the updated package(s). CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
