Raptor provides parsers for Resource Description Framework files. An XML External Entity expansion flaw was found in the way Raptor processed RDF files. If an application linked against Raptor were to open a specially-crafted RDF file, it could possibly allow a remote attacker to obtain a copy of an arbitrary local file that the user running the application had access to. A bug in the way Raptor handled external entities could cause that application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. Red Hat would like to thank Timothy D. Morgan of VSR for reporting this issue. All Raptor users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications linked against Raptor must be restarted for this update to take effect.
