Subject: CVE Request -- libvoikko -- DoS of application linked against libvoikko
 due improper handling of embedded null characters in input strings

Hello, Josh, Steve, vendors,

   A denial of service flaw was found in the way Python and Java
interfaces of libvoikko, a library for spellcheckers and hyphenators,
processed embedded null characters in input strings. If a specially-
crafted input string was provided to an application linked against
libvoikko, it could lead to that particular application termination.

Could you allocate a CVE identifier for this?

Thank you && Regards, Jan.
