Subversion (SVN) is a concurrent version control system which enables one or more users to collaborate in developing and maintaining a hierarchy of files and directories while keeping a history of all changes. The mod_dav_svn module is used with the Apache HTTP Server to allow access to Subversion repositories via HTTP.

A flaw was found in the way the mod_dav_svn module handled OPTIONS requests. A remote attacker with read access to an SVN repository served via HTTP could use this flaw to cause the httpd process that handled such a request to crash. (CVE-2014-0032)

A flaw was found in the way Subversion handled file names with newline characters when the FSFS repository format was used. An attacker with commit access to an SVN repository could corrupt a revision by committing a specially crafted file. (CVE-2013-1968)

A flaw was found in the way the svnserve tool of Subversion handled remote client network connections. An attacker with read access to an SVN repository served via svnserve could use this flaw to cause the svnserve daemon to exit, leading to a denial of service.
(CVE-2013-2112)

All subversion users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, for the update to take effect, you must restart the httpd daemon, if you are using mod_dav_svn, and the svnserve daemon, if you are serving Subversion repositories via the svn:// protocol.

The wget package provides the GNU Wget file retrieval utility for HTTP, HTTPS, and FTP protocols. Wget provides various useful features, such as the ability to work in the background while the user is logged out, recursive retrieval of directories, file name wildcard matching or updating files in dependency on file timestamp comparison.

It was discovered that wget used a file name provided by the server when saving a downloaded file. This could cause wget to create a file with a different name than expected, possibly allowing the server to execute arbitrary code on the client. (CVE-2010-2252)

Note: With this update, wget always uses the last component of the original URL as the name for the downloaded file. Previous behavior of using the server provided name or the last component of the redirected URL when creating files can be re-enabled by using the '--trust-server-names' command line option, or by setting 'trust_server_names=on' in the wget start-up file.

This update also fixes the following bugs :

* Prior to this update, the wget package did not recognize HTTPS SSL certificates with alternative names (subjectAltName) specified in the certificate as valid. As a consequence, running the wget command failed with a certificate error. This update fixes wget to recognize such certificates as valid. (BZ#1060113)

All users of wget are advised to upgrade to this updated package, which contain backported patches to correct these issues.

OpenLDAP is an open source suite of Lightweight Directory Access Protocol (LDAP) applications and development tools. LDAP is a set of protocols used to access and maintain distributed directory information services over an IP network. The openldap package contains configuration files, libraries, and documentation for OpenLDAP.

A denial of service flaw was found in the way the OpenLDAP server daemon (slapd) performed reference counting when using the rwm (rewrite/remap) overlay. A remote attacker able to query the OpenLDAP server could use this flaw to crash the server by immediately unbinding from the server after sending a search request.
(CVE-2013-4449)

Red Hat would like to thank Michael Vishchers from Seven Principles AG for reporting this issue.

This update also fixes the following bug :

* Previously, OpenLDAP did not properly handle a number of simultaneous updates. As a consequence, sending a number of parallel update requests to the server could cause a deadlock. With this update, a superfluous locking mechanism causing the deadlock has been removed, thus fixing the bug. (BZ#1056124)

All openldap users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated kernel packages that fix one security issue and three bugs are now available for Red Hat Enterprise Linux 5.

* It was found that the Xen hypervisor did not always lock 'page_alloc_lock' and 'grant_table.lock' in the same order. This could potentially lead to a deadlock. A malicious guest administrator could use this flaw to cause a denial of service on the host.
(CVE-2013-4494, Moderate)

Red Hat would like to thank the Xen project for reporting this issue.

This update also fixes the following bugs :

* A recent patch to the CIFS code that introduced the NTLMSSP (NT LAN Manager Security Support Provider) authentication mechanism caused a regression in CIFS behavior. As a result of the regression, an encryption key that is returned during the SMB negotiation protocol response was only used for the first session that was created on the SMB client. Any subsequent mounts to the same server did not use the encryption key returned by the initial negotiation with the server. As a consequence, it was impossible to mount multiple SMB shares with different credentials to the same server. A patch has been applied to correct this problem so that an encryption key or a server challenge is now provided for every SMB session during the SMB negotiation protocol response. (BZ#1029865)

* The igb driver previously used a 16-bit mask when writing values of the flow control high-water mark to hardware registers on a network device. Consequently, the values were truncated on some network devices, disrupting the flow control. A patch has been applied to the igb driver so that it now uses a 32-bit mask as expected. (BZ#1041694)

* The IPMI driver did not properly handle kernel panic messages.
Consequently, when a kernel panic occurred on a system that was utilizing IPMI without Kdump being set up, a second kernel panic could be triggered. A patch has been applied to the IPMI driver to fix this problem, and a message handler now properly waits for a response to panic event messages. (BZ#1049731)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems.

A use-after-free flaw was found in the way several libvirt block APIs handled domain jobs. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd or, potentially, execute arbitrary code with the privileges of the libvirtd process (usually root). (CVE-2013-6458)

A race condition was found in the way libvirtd handled keepalive initialization requests when the connection was closed prior to establishing connection credentials. An attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd, resulting in a denial of service. (CVE-2014-1447)

This update also fixes the following bug :

* A race condition was possible between a thread starting a virtual machine with a guest agent configured (regular start-up or while migrating) and a thread that was killing the VM process (or the process crashing). The race could cause the monitor object to be freed by the thread that killed the VM process, which was later accessed by the thread that was attempting to start the VM, resulting in a crash.
This issue was fixed by checking the state of the VM after the attempted connection to the guest agent; if the VM in the meantime exited, no other operations are attempted. (BZ#1055578)

All libvirt users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, libvirtd will be restarted automatically.
