 Package : nodejs
 Date    : March 29, 2015
 Affected: Business Server 2.0
 _______________________________________________________________________

 Problem Description:

 Updated nodejs package fixes security vulnerabilities:
 
 A memory corruption vulnerability, which results in a
 denial-of-service, was identified in the versions of V8 that ship with
 Node.js 0.8 and 0.10. In certain circumstances, a particularly deep
 recursive workload that may trigger a GC and receive an interrupt may
 overflow the stack and result in a segmentation fault. For instance,
 if your work load involves successive JSON.parse calls and the parsed
 objects are significantly deep, you may experience the process abortin

Updated stunnel package fixes security vulnerability:

A flaw was found in the way stunnel, a socket wrapper which can provide
SSL support to ordinary applications, performed (re)initialization of
PRNG after fork. When accepting a new connection, the server forks and
the child process handles the request. The RAND_bytes() function of
openssl doesn’t reset its state after the fork, but seeds the PRNG
with the output of time(NULL). The most important consequence is
that servers using EC (ECDSA) or DSA certificates may under certain
conditions leak their private key (CVE-2014-0016).

The updated packages fix this issue by using threads instead of new
processes to handle connections.

Also an issue has been corrected where the directory for the pid file
was not being created when the package is installed.

An issue currently exists in Mageia 4 where it fails trying to use
FIPS SSL (mga#13124). This can be worked around by adding fips =
no into the config.

Updated php-ZendFramework packages fix multiple vulnerabilities:

XML eXternal Entity (XXE) and XML Entity Expansion (XEE) flaws were
discovered in the Zend Framework. An attacker could use these flaws
to cause a denial of service, access files accessible to the server
process, or possibly perform other more advanced XML External Entity
(XXE) attacks (CVE-2014-2681, CVE-2014-2682, CVE-2014-2683).

Using the Consumer component of Zend_OpenId, it is possible to
login using an arbitrary OpenID account (without knowing any secret
information) by using a malicious OpenID Provider. That means OpenID it
is possible to login using arbitrary OpenID Identity (MyOpenID, Google,
etc), which are not under the control of our own OpenID Provider. Thus,
we are able to impersonate any OpenID Identity against the framework
(CVE-2014-2684, CVE-2014-2685).

The implementation of the ORDER BY SQL statement in Zend_Db_Select
of Zend Framework 1 contains a potential SQL injection when the query
string passed contains parentheses (CVE-2014-4914).

Due to a bug in PHP’s LDAP extension, when ZendFramework’s Zend_ldap
class is used for logins, an attacker can login as any user by
using a null byte to bypass the empty password check and perform an
unauthenticated LDAP bind (CVE-2014-8088).

The sqlsrv PHP extension, which provides the ability to connect to
Microsoft SQL Server from PHP, does not provide a built-in quoting
mechanism for manually quoting values to pass via SQL queries;
developers are encouraged to use prepared statements. Zend Framework
provides quoting mechanisms via Zend_Db_Adapter_Sqlsrv which uses
the recommended double single quote (”) as quoting delimiters. SQL
Server treats null bytes in a query as a string terminator, allowing
an attacker to add arbitrary SQL following a null byte, and thus
create a SQL injection (CVE-2014-8089).

Updated net-snmp packages fix security vulnerabilities:

Remotely exploitable denial of service vulnerability in Net-SNMP,
in the Linux implementation of the ICMP-MIB, making the SNMP
agent vulnerable if it is making use of the ICMP-MIB table objects
(CVE-2014-2284).

Remotely exploitable denial of service vulnerability in Net-SNMP,
in snmptrapd, due to how it handles trap requests with an empty
community string when the perl handler is enabled (CVE-2014-2285).

A remote denial-of-service flaw was found in the way snmptrapd handled
certain SNMP traps when started with the -OQ option. If an attacker
sent an SNMP trap containing a variable with a NULL type where an
integer variable type was expected, it would cause snmptrapd to crash
(CVE-2014-3565).

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
(CVE-2014-0117).

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
(CVE-2014-3581).

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
(CVE-2014-8109).

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
(CVE-2013-5704).

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 aforementioned flaw.

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
(rhbz#1141950).

Updated nginx package fixes security vulnerabilities:

A bug in the experimental SPDY implementation in nginx was found,
which might allow an attacker to cause a heap memory buffer overflow
in a worker process by using a specially crafted request, potentially
resulting in arbitrary code execution (CVE-2014-0133).

Antoine Delignat-Lavaud and Karthikeyan Bhargavan discovered that
it was possible to reuse cached SSL sessions in unrelated contexts,
allowing virtual host confusion attacks in some configurations by an
attacker in a privileged network position (CVE-2014-3616).
