[USN-4630-1] Raptor vulnerability

raptor2 vulnerability

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

- Ubuntu 20.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS


raptor2 could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- raptor2: RDF syntax library


Hanno Böck discovered that Raptor incorrectly handled certain memory
operations. If a user were tricked into opening a specially crafted
document in an application linked against Raptor, an attacker could
cause the application to crash, resulting in a denial of service, or
possibly execute arbitrary code.

Update instructions:

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

Ubuntu 20.10:
  libraptor2-0                    2.0.15-0ubuntu1.20.10.1

Ubuntu 20.04 LTS:
  libraptor2-0                    2.0.15-0ubuntu1.20.04.1

Ubuntu 18.04 LTS:
  libraptor2-0                    2.0.14-1ubuntu0.18.04.1

Ubuntu 16.04 LTS:
  libraptor2-0                    2.0.14-1ubuntu0.16.04.1

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