Subject: [USN-1480-1] Raptor vulnerability
Message-ID: <1340035693.3336.11.camel@localhost>
Content-Type: text/plain; charset="utf-8"

==========================================================================
Ubuntu Security Notice USN-1480-1
June 18, 2012

raptor vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 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:
- raptor: Raptor RDF parser and serializer 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:
libraptor1 1.4.21-7ubuntu0.1

Ubuntu 11.10:
libraptor1 1.4.21-5ubuntu0.1

Ubuntu 11.04:
libraptor1 1.4.21-2ubuntu0.1

Ubuntu 10.04 LTS:
libraptor1 1.4.21-1ubuntu1.1

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