   An update that solves two vulnerabilities and has one
   errata is now available.

Description:


   This update fixes the following security issues:

   - Enforce receive packet size, thus eliminating buffer overflow and
     potential security issue. (bsc#957162 CVE-2015-7512)
   - Infinite loop in processing command block list. CVE-2015-8345
     (bsc#956829):

   This update also fixes a non-security bug:

     supported guests are negatively impacted by this change, which is taken
     from upstream seabios)
