Red Hat Security Advisory 2013-0499-02 - The xinetd package provides a secure replacement for inetd, the Internet services daemon. xinetd provides access control for all services based on the address of the remote host and/or on time of access, and can prevent denial-of-access attacks. When xinetd services are configured with the "TCPMUX" or "TCPMUXPLUS" type, and the tcpmux-server service is enabled, those services are accessible via port 1. It was found that enabling the tcpmux-server service allowed every xinetd service, including those that are not configured with the "TCPMUX" or "TCPMUXPLUS" type, to be accessible via port 1. This could allow a remote attacker to bypass intended firewall restrictions.

This update fixes one vulnerability in Adobe Flash Player. This vulnerability is detailed on the Adobe security page APSB12-18, listed in the References section. Specially-crafted SWF content could cause flash-plugin to crash or, potentially, execute arbitrary code when a victim loads a page containing the malicious SWF content. All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 11.2.202.238.

It provides a job queuing mechanism, scheduling policy, priority scheme, and resource monitoring and management. Condor installations that rely solely upon host-based authentication were vulnerable to an attacker who controls an IP, its reverse-DNS entry and has knowledge of a target site's security configuration. With this control and knowledge, the attacker could bypass the target site's host-based authentication and be authorized to perform privileged actions. Condor deployments using host-based authentication that contain no hostnames or use authentication stronger than host-based are not vulnerable.

An integer overflow flaw was found in the i915_gem_execbuffer2() function in the Intel i915 driver in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service. This issue only affected 32-bit systems. A missing initialization flaw was found in the sco_sock_getsockopt_old() function in the Linux kernel's Bluetooth implementation. A local, unprivileged user could use this flaw to cause an information leak.

It can use the AJP, HTTP, or HTTPS protocols for communication with application server nodes. The RHSA-2012:0035 update for JBoss Enterprise Web Server 1.0.2 introduced a regression, causing mod_cluster to register and expose the root context of a server by default, even when "ROOT" was in the "excludedContexts" list in the mod_cluster configuration. If an application was deployed on the root context, a remote attacker could use this flaw to bypass intended access restrictions and gain access to that application.

This roll up patch serves as a cumulative upgrade for JBoss Enterprise BRMS Platform 5.3.0. It includes various bug fixes. The following security issue is also fixed with this release: It was found that the JMX Console did not protect against Cross-Site Request Forgery attacks. If a remote attacker could trick a user, who was logged into the JMX Console, into visiting a specially-crafted URL, the attacker could perform operations on MBeans, which may lead to arbitrary code execution in the context of the JBoss server process.

A memory leak flaw was found in the way the Linux kernel's memory subsystem handled resource clean up in the mmap() failure path when the MAP_HUGETLB flag was set. A local, unprivileged user could use this flaw to cause a denial of service. A flaw was found in the way the Linux kernel's Event Poll subsystem handled resource clean up when an ELOOP error code was returned. A local, unprivileged user could use this flaw to cause a denial of service.

It was found that the OpenLDAP server daemon ignored olcTLSCipherSuite settings. This resulted in the default cipher suite always being used, which could lead to weaker than expected ciphers being accepted during Transport Layer Security negotiation with OpenLDAP clients.

An insecure temporary file use flaw was found in the sudo package's post-uninstall script. A local attacker could possibly use this flaw to overwrite an arbitrary file via a symbolic link attack, or modify the contents of the "/etc/nsswitch.conf" file during the upgrade or removal of the sudo package. This update also fixes the following bugs:

This update fixes the following security issue: A NULL pointer dereference flaw was found in the nf_ct_frag6_reasm() function in the Linux kernel's netfilter IPv6 connection tracking implementation.

It features support for dynamic updates and internal caching that help to reduce the load on LDAP servers. A flaw was found in the way bind-dyndb-ldap performed the escaping of names from DNS requests for use in LDAP queries. A remote attacker able to send DNS queries to a named server that is configured to use bind-dyndb-ldap could use this flaw to cause named to exit unexpectedly with an assertion failure.

A denial of service flaw was found in the way the dhcpd daemon handled zero-length client identifiers. A remote attacker could use this flaw to send a specially-crafted request to dhcpd, possibly causing it to enter an infinite loop and consume an excessive amount of CPU time. Two memory leak flaws were found in the dhcpd daemon. A remote attacker could use these flaws to cause dhcpd to exhaust all available memory by sending a large number of DHCP requests.

Multiple heap-based buffer overflow flaws were found in the way OpenOffice.org processed encryption information in the manifest files of OpenDocument Format files.

A flaw was found in the way the pyGrub boot loader handled compressed kernel images. A privileged guest user in a para-virtualized guest could use this flaw to create a crafted kernel image that, when attempting to boot it, could result in an out-of-memory condition in the privileged domain.

It also contains a configuration tool for managing deployment settings for the plug-in and Web Start implementations. An uninitialized pointer use flaw was found in the IcedTea-Web plug-in. Visiting a malicious web page could possibly cause a web browser using the IcedTea-Web plug-in to crash, disclose a portion of its memory, or execute arbitrary code. It was discovered that the IcedTea-Web plug-in incorrectly assumed all strings received from the browser were NUL terminated. When using the plug-in with a web browser that does not NUL terminate strings, visiting a web page containing a Java applet could possibly cause the browser to crash, disclose a portion of its memory, or execute arbitrary code.

An uninitialized pointer use flaw was found in the way the MIT Kerberos KDC handled initial authentication requests. A remote, unauthenticated attacker could use this flaw to crash the KDC via a specially-crafted AS-REQ request. A NULL pointer dereference flaw was found in the MIT Kerberos administration daemon, kadmind. A Kerberos administrator who has the "create" privilege could use this flaw to crash kadmind.
