We apologize for the inconvenience.
Original advisory details:
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. (CVE-2013-0339)
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)";
