Ubuntu Security Notice USN-1901-1

raptor2 vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

Applications using Raptor could be made to expose sensitive information or
run programs as your login if they opened a specially crafted file.

Software Description:
- raptor2: Raptor 2 RDF syntax library

Details:

Timothy D. Morgan discovered that Raptor would unconditionally load XML
external entities. If a user were tricked into opening a specially crafted
document in an application linked against Raptor, an attacker could
possibly obtain access to arbitrary files on the user's system or
potentially execute arbitrary code with the privileges of the user invoking
the program.

Update instructions:

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

Ubuntu 12.04 LTS:
  libraptor2-0                    2.0.6-1ubuntu0.1

After a standard system update you need to restart any applications which
use Raptor, such as LibreOffice, to make all the necessary changes.
