"A race condition flaw, leading to heap-based buffer overflows, was
found in the mod_status httpd module. A remote attacker able to access
a status page served by mod_status on a server using a threaded
Multi-Processing Module (MPM) could send a specially crafted request
that would cause the httpd child process to crash or, possibly, allow
the attacker to execute arbitrary code with the privileges of the
'apache' user. (CVE-2014-0226)

A denial of service flaw was found in the way httpd's mod_deflate
module handled request body decompression (configured via the
'DEFLATE' input filter). A remote attacker able to send a request
whose body would be decompressed could use this flaw to consume an
excessive amount of system memory and CPU on the target system.
(CVE-2014-0118)

A denial of service flaw was found in the way httpd's mod_cgid module
executed CGI scripts that did not read data from the standard input. A
remote attacker could submit a specially crafted request that would
cause the httpd child process to hang indefinitely. (CVE-2014-0231)

After installing the updated packages, the httpd daemon will be
restarted automatically."
