The httpd packages provide the Apache HTTP Server, a powerful, efficient,and extensible web server.A race condition flaw, leading to heap-based buffer overflows, was found inthe mod_status httpd module. A remote attacker able to access a status pageserved by mod_status on a server using a threaded Multi-Processing Module(MPM) could send a specially crafted request that would cause the httpdchild process to crash or, possibly, allow the attacker to executearbitrary code with the privileges of the "apache" user. (CVE-2014-0226)A NULL pointer dereference flaw was found in the mod_cache httpd module.A malicious HTTP server could cause the httpd child process to crash whenthe Apache HTTP Server was used as a forward proxy with caching.(CVE-2013-4352)A denial of service flaw was found in the mod_proxy httpd module. A remoteattacker could send a specially crafted request to a server configured as areverse proxy using a threaded Multi-Processing Modules (MPM) that wouldcause the httpd child process to crash. (CVE-2014-0117)A denial of service flaw was found in the way httpd's mod_deflate modulehandled request body decompression (configured via the "DEFLATE" inputfilter). A remote attacker able to send a request whose body would bedecompressed could use this flaw to consume an excessive amount of systemmemory and CPU on the target system. (CVE-2014-0118)A denial of service flaw was found in the way httpd's mod_cgid moduleexecuted CGI scripts that did not read data from the standard input.A remote attacker could submit a specially crafted request that would causethe httpd child process to hang indefinitely. (CVE-2014-0231)All httpd users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues. After installing theupdated packages, the httpd daemon will be restarted automatically.
