CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. * A denial of service flaw was found in the way the Linux kernel's IPv6 implementation processed IPv6 router advertisement (RA) packets. An attacker able to send a large number of RA packets to a target system could potentially use this flaw to crash the target system. (CVE-2014-2309, Important) * A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol (DCCP) packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2523, Important) * A flaw was found in the way the Linux kernel's CIFS implementation handled uncached write operations with specially crafted iovec structures. An unprivileged local user with access to a CIFS share could use this flaw to crash the system, leak kernel memory, or, potentially, escalate their privileges on the system. (CVE-2014-0069, Moderate) * A flaw was found in the way the Linux kernel handled pending Floating Pointer Unit (FPU) exceptions during the switching of tasks. A local attacker could use this flaw to terminate arbitrary processes on the system, causing a denial of service, or, potentially, escalate their privileges on the system. Note that this flaw only affected systems using AMD CPUs on both 32-bit and 64-bit architectures. (CVE-2014-1438, Moderate) * It was found that certain protocol handlers in the Linux kernel's networking implementation could set the addr_len value without initializing the associated data structure. A local, unprivileged user could use this flaw to leak kernel stack memory to user space using the recvmsg, recvfrom, and recvmmsg system calls. (CVE-2013-7263, CVE-2013-7265, Low) * An information leak flaw was found in the Linux kernel's netfilter connection tracking IRC NAT helper implementation that could allow a remote attacker to disclose portions of kernel stack memory during IRC DCC (Direct Client-to-Client) communication over NAT. (CVE-2014-1690, Low) * A denial of service flaw was discovered in the way the Linux kernel's SELinux implementation handled files with an empty SELinux security context. A local user who has the CAP_MAC_ADMIN capability could use this flaw to crash the system. (CVE-2014-1874, Low) This update also fixes several bugs and adds multiple enhancements. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.33, correct these issues, and fix the bugs and add the enhancements noted in the Red Hat Enterprise MRG 2 Technical Notes. The system must be rebooted for this update to take effect.

    description The Linux Kernel was updated to fix various security issues and bugs. Main security issues fixed : A security issue in the tty layer that was fixed that could be used by local attackers for code execution (CVE-2014-0196). Two security issues in the floppy driver were fixed that could be used by local attackers on machines with the floppy to crash the kernel or potentially execute code in the kernel (CVE-2014-1737 CVE-2014-1738). Other security issues and bugs that were fixed : - netfilter: nf_nat: fix access to uninitialized buffer in IRC NAT helper (bnc#860835 CVE-2014-1690). - net: sctp: fix sctp_sf_do_5_1D_ce to verify if we/peer is AUTH (bnc#866102, CVE-2014-0101). - n_tty: Fix a n_tty_write crash and code execution when echoing in raw mode (bnc#871252 bnc#875690 CVE-2014-0196). - netfilter: nf_ct_sip: support Cisco 7941/7945 IP phones (bnc#873717). - Update config files: re-enable twofish crypto support Software twofish crypto support was disabled in several architectures since openSUSE 10.3. For i386 and x86_64 it was on purpose, because hardware-accelerated alternatives exist. However for all other architectures it was by accident. Re-enable software twofish crypto support in arm, ia64 and ppc configuration files, to guarantee that at least one implementation is always available (bnc#871325). - Update config files: disable CONFIG_TOUCHSCREEN_W90X900 The w90p910_ts driver only makes sense on the W90x900 architecture, which we do not support. - ath9k: protect tid->sched check (bnc#871148,CVE-2014-2672). - Fix dst_neigh_lookup/dst_neigh_lookup_skb return value handling bug (bnc#869898). - SELinux: Fix kernel BUG on empty security contexts (bnc#863335,CVE-2014-1874). - hamradio/yam: fix info leak in ioctl (bnc#858872, CVE-2014-1446). - wanxl: fix info leak in ioctl (bnc#858870, CVE-2014-1445). - farsync: fix info leak in ioctl (bnc#858869, CVE-2014-1444). - ARM: 7809/1: perf: fix event validation for software group leaders (CVE-2013-4254, bnc#837111). - netfilter: nf_conntrack_dccp: fix skb_header_pointer API usages (bnc#868653, CVE-2014-2523). - ath9k_htc: properly set MAC address and BSSID mask (bnc#851426, CVE-2013-4579). - drm/ttm: don't oops if no invalidate_caches() (bnc#869414). - Apply missing patches.fixes/drm-nouveau-hwmon-rename-fan0-to-fan1.patc h - xfs: growfs: use uncached buffers for new headers (bnc#858233). - xfs: use btree block initialisation functions in growfs (bnc#858233). - Revert 'Delete patches.fixes/xfs-fix-xfs_buf_find-oops-on-blocks-beyond -the-filesystem-end.' (bnc#858233) Put back again the patch patches.fixes/xfs-fix-xfs_buf_find-oops-on-blocks-beyond -the-filesystem-end back as there is a better fix than reverting the affecting patch. - Delete patches.fixes/xfs-fix-xfs_buf_find-oops-on-blocks-beyond -the-filesystem-end. It turned out that this patch causes regressions (bnc#858233) The upstream 3.7.x also reverted it in the end (commit c3793e0d94af2). - tcp: syncookies: reduce cookie lifetime to 128 seconds (bnc#833968). - tcp: syncookies: reduce mss table to four values (bnc#833968). - x86, cpu, amd: Add workaround for family 16h, erratum 793 (bnc#852967 CVE-2013-6885). - cifs: ensure that uncached writes handle unmapped areas correctly (bnc#864025 CVE-2014-0691). - x86, fpu, amd: Clear exceptions in AMD FXSAVE workaround (bnc#858638 CVE-2014-1438). - xencons: generalize use of add_preferred_console() (bnc#733022, bnc#852652). - balloon: don't crash in HVM-with-PoD guests. - hwmon: (coretemp) Fix truncated name of alarm attributes. - NFS: Avoid PUTROOTFH when managing leases (bnc#811746). - cifs: delay super block destruction until all cifsFileInfo objects are gone (bnc#862145).
