libxml2 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
libxml2 could be made to crash if it opened a specially crafted file.
Software Description: - libxml2: GNOME XML library
Details:
Wei Lei discovered that libxml2 incorrecty handled certain parameter entities. An attacker could use this issue with specially constructed XML data to cause libxml2 to consume resources, leading to a denial of service.
