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

  - Fixed a scoreboard corruption (shared mem segment) by
    child causes crash of privileged parent (invalid free())
    during shutdown. (CVE-2012-0031)

  - Fixed an issue in error responses that could expose
    'httpOnly' cookies when no custom ErrorDocument is
    specified for status code 400'. (CVE-2012-0053)

  - 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. (CVE-2007-6750)

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)"
