The remote Mandriva Linux host is missing one or more security
Updated apache packages fix security vulnerabilities :
Apache HTTPD before 2.4.9 was vulnerable to a denial of service in
mod_dav when handling DAV_WRITE requests (CVE-2013-6438).
Apache HTTPD before 2.4.9 was vulnerable to a denial of service when
logging cookies (CVE-2014-0098).
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 mod_proxy httpd module. A
remote attacker could send a specially crafted request to a server
configured as a reverse proxy using a threaded Multi-Processing
Modules (MPM) that would cause the httpd child process to crash
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).
A NULL pointer dereference flaw was found in the way the mod_cache
httpd module handled Content-Type headers. A malicious HTTP server
could cause the httpd child process to crash when the Apache HTTP
server was configured to proxy to a server with caching enabled
mod_lua.c in the mod_lua module in the Apache HTTP Server through
2.4.10 does not support an httpd configuration in which the same Lua
authorization provider is used with different arguments within
different contexts, which allows remote attackers to bypass intended
access restrictions in opportunistic circumstances by leveraging
multiple Require directives, as demonstrated by a configuration that
specifies authorization for one group to access a certain directory,
and authorization for a second group to access a second directory
In the mod_lua module in the Apache HTTP Server through 2.4.10, a
maliciously crafted websockets PING after a script calls r:wsupgrade()
can cause a child process crash (CVE-2015-0228).
A flaw was found in the way httpd handled HTTP Trailer headers when
processing requests using chunked encoding. A malicious client could
use Trailer headers to set additional HTTP headers after header
processing was performed by other modules. This could, for example,
lead to a bypass of header restrictions defined with mod_headers
Note: With this update, httpd has been modified to not merge HTTP
Trailer headers with other HTTP request headers. A newly introduced
configuration directive MergeTrailers can be used to re-enable the old
method of processing Trailer headers, which also re-introduces the
This update also fixes the following bug :
Prior to this update, the mod_proxy_wstunnel module failed to set up
an SSL connection when configured to use a back end server using the
wss: URL scheme, causing proxied connections to fail. In these updated
packages, SSL is used when proxying to wss: back end servers
