An update that solves three vulnerabilities and has four
fixes is now available. It includes one version update.
Description:
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
