Description

This update for the Apache Web Server provides the following fixes :

  • Fixed a heap-based buffer overflow on apache module mod_status. (bnc#887765, CVE-2014-0226)

  • Properly remove whitespace characters from CDATA sections to avoid remote denial of service by crashing the Apache Server process. (bnc#869105, CVE-2013-6438)

  • Correction to parsing of cookie content; this can lead to a crash with a specially designed cookie sent to the server. (bnc#869106, CVE-2014-0098)

  • ECC support should not be missing. (bnc#859916) This update also introduces a new configuration parameter CGIDScriptTimeout, which defaults to the value of parameter Timeout. CGIDScriptTimeout is set to 60s if mod_cgid is loaded/active, via /etc/apache2/conf.d/cgid-timeout.conf. The new directive and its effect prevent request workers to be eaten until starvation if cgi programs do not send output back to the server within the timeout set by CGIDScriptTimeout. (bnc#887768, CVE-2014-0231)
