Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
USN-1904-1 fixed vulnerabilities in libxml2. The update caused a
regression for certain users. This update fixes the problem.
We apologize for the inconvenience.
It was discovered that libxml2 would load XML external entities by
default. If a user or automated system were tricked into opening a
specially crafted document, an attacker could possibly obtain access
to arbitrary files or cause resource consumption. This issue only
affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS, and Ubuntu 12.10.
It was discovered that libxml2 incorrectly handled documents
that end abruptly. If a user or automated system were
tricked into opening a specially crafted document, an
attacker could possibly cause libxml2 to crash, resulting in
a denial of service. (CVE-2013-2877).
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected libxml2 package.
