      Description

      **Reported in Launchpad by Stewart Smith last update 02-06-2013 14:56:03

      MySQL bug 13889741 (which is CVE-2012-3163) was, apparently, not completely fixed. A very similar test case finds new, much more dangerous, buffer overflows in acl_get() and check_grant_db_routine(). They allow to overwrite the buffer by an arbitrary number of bytes, not just by one as in bug 13889741. One can trivially put a shellcode there.

      To exploit this one needs a valid low-privileged user account in the MariaDB (or MySQL) server.

      This new vulnerability is registered as CVE-2012-5579
