Description:

   These security issues were fixed:

   - CVE-2018-6196: Prevent infinite recursion in HTMLlineproc0 caused by the

     value (bsc#1077559)

     (bsc#1077568)
   - CVE-2018-6198: w3m did not properly handle temporary files when the

     a symlink attack to overwrite arbitrary files (bsc#1077572)
