USN-1480-1: Raptor vulnerability

18 June 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


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


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.
