Security update for Apache2 (important)


0.717 High




This update of apache2 and libapr1 fixes regressions and
several security problems.

  • CVE-2012-0031: Fixed a scoreboard corruption (shared
    mem segment) by child causes crash of privileged parent
    (invalid free()) during shutdown.
  • CVE-2012-0053: Fixed an issue in error responses that
    could expose "httpOnly" cookies when no custom
    ErrorDocument is specified for status code 400".
  • CVE-2007-6750: The "mod_reqtimeout" module was
    backported from Apache 2.2.21 to help mitigate the
    "Slowloris" Denial of Service attack.

You need to enable the "mod_reqtimeout" module in your
existing apache configuration to make it effective, e.g.
in the APACHE_MODULES line in /etc/sysconfig/apache2. For
more detailed information, check also the README file.

Also the following bugs have been fixed:

  • Fixed init script action "check-reload" to avoid
    potential crashes. bnc#728876
  • An overlapping memcpy() was replaced by memmove() to
    make this work with newer glibcs. bnc#738067 bnc#741874
  • libapr1: reset errno to zero to not return previous
    value despite good status of new operation. bnc#739783
