On openSUSE 12.2, nginx was updated to version 1.4.4 stable

  • CVE-2013-4547 a character following an unescaped space in a request line was handled incorrectly [bnc#851295]

  • bugfix: segmentation fault might occur in the spdy module

  • bugfix: segmentation fault might occur on start if if the ‘try_files’ directive was used with an empty parameter.
