Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS - Ubuntu 13.10 - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS

Summary:

USN-2214-1 introduced a regression in libxml2.

Software Description: - libxml2: GNOME XML library

Details:

USN-2214-1 fixed vulnerabilities in libxml2. The upstream fix introduced a number of regressions. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Daniel Berrange discovered that libxml2 would incorrectly perform entity
substitution even when requested not to. If a user or automated system were
tricked into opening a specially crafted document, an attacker could
possibly cause resource consumption, resulting in a denial of service.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 LTS:
libxml2 2.9.1+dfsg1-3ubuntu4.3

Ubuntu 13.10:
libxml2 2.9.1+dfsg1-3ubuntu2.3

Ubuntu 12.04 LTS:
libxml2 2.7.8.dfsg-5.1ubuntu4.9

Ubuntu 10.04 LTS:
libxml2 2.7.6.dfsg-1ubuntu1.13

In general, a standard system update will make all the necessary changes.
