ID CVE-2009-1338
Summary The kill_something_info function in kernel/signal.c in the Linux kernel before 2.6.28 does not consider PID namespaces when processing signals directed to PID -1, which allows local users to bypass the intended namespace isolation, and send arbitrary signals to all processes in all namespaces, via a kill command.

Impact:
Exploitability:
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.

    description Igor Zhbanov discovered that NFS clients were able to create device nodes even when root_squash was enabled. An authenticated remote attacker could create device nodes with open permissions, leading to a loss of privacy or escalation of privileges. Only Ubuntu 8.10 and 9.04 were affected. (CVE-2009-1072) Dan Carpenter discovered that SELinux did not correctly handle certain network checks when running with compat_net=1. A local attacker could exploit this to bypass network checks. Default Ubuntu installations do not enable SELinux, and only Ubuntu 8.10 and 9.04 were affected. (CVE-2009-1184) Shaohua Li discovered that memory was not correctly initialized in the AGP subsystem. A local attacker could potentially read kernel memory, leading to a loss of privacy. (CVE-2009-1192) Benjamin Gilbert discovered that the VMX implementation of KVM did not correctly handle certain registers. An attacker in a guest VM could exploit this to cause a host system crash, leading to a denial of service. This only affected 32bit hosts. Ubuntu 6.06 was not affected. (CVE-2009-1242) Thomas Pollet discovered that the Amateur Radio X.25 Packet Layer Protocol did not correctly validate certain fields. A remote attacker could exploit this to read kernel memory, leading to a loss of privacy. (CVE-2009-1265) Trond Myklebust discovered that NFS did not correctly handle certain long filenames. An authenticated remote attacker could exploit this to cause a system crash, leading to a denial of service. Only Ubuntu 6.06 was affected. (CVE-2009-1336) Oleg Nesterov discovered that the kernel did not correctly handle CAP_KILL. A local user could exploit this to send signals to arbitrary processes, leading to a denial of service. (CVE-2009-1337) Daniel Hokka Zakrisson discovered that signal handling was not correctly limited to process namespaces. A local user could bypass namespace restrictions, possibly leading to a denial of service. Only Ubuntu 8.04 was affected. (CVE-2009-1338) Pavel Emelyanov discovered that network namespace support for IPv6 was not correctly handled. A remote attacker could send specially crafted IPv6 traffic that would cause a system crash, leading to a denial of service. Only Ubuntu 8.10 and 9.04 were affected. (CVE-2009-1360) Neil Horman discovered that the e1000 network driver did not correctly validate certain fields. A remote attacker could send a specially crafted packet that would cause a system crash, leading to a denial of service. (CVE-2009-1385) Pavan Naregundi discovered that CIFS did not correctly check lengths when handling certain mount requests. A remote attacker could send specially crafted traffic to cause a system crash, leading to a denial of service. (CVE-2009-1439) Simon Vallet and Frank Filz discovered that execute permissions were not correctly handled by NFSv4. A local user could bypass permissions and run restricted programs, possibly leading to an escalation of privileges. (CVE-2009-1630) Jeff Layton and Suresh Jayaraman discovered buffer overflows in the CIFS client code. A malicious remote server could exploit this to cause a system crash or execute arbitrary code as root. (CVE-2009-1633) Mikulas Patocka discovered that /proc/iomem was not correctly initialized on Sparc. A local attacker could use this file to crash the system, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-1914) Miklos Szeredi discovered that OCFS2 did not correctly handle certain splice operations. A local attacker could exploit this to cause a system hang, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-1961). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
