Synopsis: Important: httpd security update
Advisory ID: SLSA-2014:0920-1
Issue Date: 2014-07-23
CVE Numbers: CVE-2014-0231
 CVE-2014-0118
 CVE-2014-0226
--

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.
