Summary

The Linux kernel 2.6.33.2 and earlier, when a ReiserFS filesystem exists, does not restrict read or write access to the .reiserfs_priv directory, which allows local users to gain privileges by modifying (1) extended attributes or (2) ACLs, as demonstrated by deleting a file under .reiserfs_priv/xattrs/.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (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.

    descriptionUSN-947-1 fixed vulnerabilities in the Linux kernel. Fixes for CVE-2010-0419 caused failures when using KVM in certain situations. This update reverts that fix until a better solution can be found. We apologize for the inconvenience. It was discovered that the Linux kernel did not correctly handle memory protection of the Virtual Dynamic Shared Object page when running a 32-bit application on a 64-bit kernel. A local attacker could exploit this to cause a denial of service. (Only affected Ubuntu 6.06 LTS.) (CVE-2009-4271) It was discovered that the r8169 network driver did not correctly check the size of Ethernet frames. A remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. (CVE-2009-4537) Wei Yongjun discovered that SCTP did not correctly validate certain chunks. A remote attacker could send specially crafted traffic to monopolize CPU resources, leading to a denial of service. (Only affected Ubuntu 6.06 LTS.) (CVE-2010-0008) It was discovered that KVM did not correctly limit certain privileged IO accesses on x86. Processes in the guest OS with access to IO regions could gain further privileges within the guest OS. (Did not affect Ubuntu 6.06 LTS.)

    descriptionThis openSUSE 11.2 kernel was updated to 2.6.31.14, fixing several security issues and bugs. A lot of ext4 filesystem stability fixes were also added. Following security issues have been fixed: CVE-2010-3301: Mismatch between 32bit and 64bit register usage in the system call entry path could be used by local attackers to gain root privileges. This problem only affects x86_64 kernels. CVE-2010-3081: Incorrect buffer handling in the biarch-compat buffer handling could be used by local attackers to gain root privileges. This problem affects foremost x86_64, or potentially other biarch platforms, like PowerPC and S390x. CVE-2010-3084: A buffer overflow in the ETHTOOL_GRXCLSRLALL code could be used to crash the kernel or potentially execute code. CVE-2010-2955: A kernel information leak via the WEXT ioctl was fixed. CVE-2010-2960: The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel expects that a certain parent session keyring exists, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function. CVE-2010-3080: A double free in an alsa error path was fixed, which could lead to kernel crashes. CVE-2010-3079: Fixed a ftrace NULL pointer dereference problem which could lead to kernel crashes. CVE-2010-3298: Fixed a kernel information leak in the net/usb/hso driver. CVE-2010-3296: Fixed a kernel information leak in the cxgb3 driver. CVE-2010-3297: Fixed a kernel information leak in the net/eql driver. CVE-2010-3078: Fixed a kernel information leak in the xfs filesystem. CVE-2010-2942: Fixed a kernel information leak in the net scheduler code. CVE-2010-2954: The irda_bind function in net/irda/af_irda.c in the Linux kernel did not properly handle failure of the irda_open_tsap function, which allowed local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact via multiple unsuccessful calls to bind on an AF_IRDA (aka PF_IRDA) socket. CVE-2010-2226: The xfs_swapext function in fs/xfs/xfs_dfrag.c in the Linux kernel did not properly check the file descriptors passed to the SWAPEXT ioctl, which allowed local users to leverage write access and obtain read access by swapping one file into another file.

    descriptionIt was discovered that the Linux kernel did not correctly handle memory protection of the Virtual Dynamic Shared Object page when running a 32-bit application on a 64-bit kernel. A local attacker could exploit this to cause a denial of service. (Only affected Ubuntu 6.06 LTS.) (CVE-2009-4271) It was discovered that the r8169 network driver did not correctly check the size of Ethernet frames. A remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. (CVE-2009-4537) Wei Yongjun discovered that SCTP did not correctly validate certain chunks. A remote attacker could send specially crafted traffic to monopolize CPU resources, leading to a denial of service. (Only affected Ubuntu 6.06 LTS.) (CVE-2010-0008) It was discovered that KVM did not correctly limit certain privileged IO accesses on x86. Processes in the guest OS with access to IO regions could gain further privileges within the guest OS. (Did not affect Ubuntu 6.06 LTS.) (CVE-2010-0298, CVE-2010-0306, CVE-2010-0419) Evgeniy Polyakov discovered that IPv6 did not correctly handle certain TUN packets. A remote attacker could exploit this to crash the system, leading to a denial of service. (Only affected Ubuntu 8.04 LTS.) (CVE-2010-0437) Sachin Prabhu discovered that GFS2 did not correctly handle certain locks. A local attacker with write access to a GFS2 filesystem could exploit this to crash the system, leading to a denial of service. (CVE-2010-0727) Jamie Strandboge discovered that network virtio in KVM did not correctly handle certain high-traffic conditions. A remote attacker could exploit this by sending specially crafted traffic to a guest OS, causing the guest to crash, leading to a denial of service. (Only affected Ubuntu 8.04 LTS.) (CVE-2010-0741) Marcus Meissner discovered that the USB subsystem did not correctly handle certain error conditions. A local attacker with access to a USB device could exploit this to read recently used kernel memory, leading to a loss of privacy and potentially root privilege escalation. (CVE-2010-1083) Neil Brown discovered that the Bluetooth subsystem did not correctly handle large amounts of traffic. A physically proximate remote attacker could exploit this by sending specially crafted traffic that would consume all available system memory, leading to a denial of service. (Ubuntu 6.06 LTS and 10.04 LTS were not affected.) (CVE-2010-1084) Jody Bruchon discovered that the sound driver for the AMD780V did not correctly handle certain conditions. A local attacker with access to this hardward could exploit the flaw to cause a system crash, leading to a denial of service. (CVE-2010-1085) Ang Way Chuang discovered that the DVB driver did not correctly handle certain MPEG2-TS frames. An attacker could exploit this by delivering specially crafted frames to monopolize CPU resources, leading to a denial of service. (Ubuntu 10.04 LTS was not affected.) (CVE-2010-1086) Trond Myklebust discovered that NFS did not correctly handle truncation under certain conditions. A local attacker with write access to an NFS share could exploit this to crash the system, leading to a denial of service. (Ubuntu 10.04 LTS was not affected.) (CVE-2010-1087) Al Viro discovered that automount of NFS did not correctly handle symlinks under certain conditions. A local attacker could exploit this to crash the system, leading to a denial of service. (Ubuntu 6.06 LTS and Ubuntu 10.04 LTS were not affected.) (CVE-2010-1088) Matt McCutchen discovered that ReiserFS did not correctly protect xattr files in the .reiserfs_priv directory. A local attacker could exploit this to gain root privileges or crash the system, leading to a denial of service. (CVE-2010-1146) Eugene Teo discovered that CIFS did not correctly validate arguments when creating new files. A local attacker could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges if mmap_min_addr was not set. (CVE-2010-1148) Catalin Marinas and Tetsuo Handa discovered that the TTY layer did not correctly release process IDs. A local attacker could exploit this to consume kernel resources, leading to a denial of service. (CVE-2010-1162) Neil Horman discovered that TIPC did not correctly check its internal state. A local attacker could send specially crafted packets via AF_TIPC that would cause the system to crash, leading to a denial of service. (Ubuntu 6.06 LTS was not affected.) (CVE-2010-1187) Masayuki Nakagawa discovered that IPv6 did not correctly handle certain settings when listening. If a socket were listening with the IPV6_RECVPKTINFO flag, a remote attacker could send specially crafted traffic that would cause the system to crash, leading to a denial of service. (Only Ubuntu 6.06 LTS was affected.) (CVE-2010-1188) Oleg Nesterov discovered that the Out-Of-Memory handler did not correctly handle certain arrangements of processes. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-1488). 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.
