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 This kernel update for openSUSE 10.3 fixes some bugs and several security problems. The following security issues are fixed: A local denial of service problem in the splice(2) system call. CVE-2009-0834: The audit_syscall_entry function in the Linux kernel on the x86_64 platform did not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls.

CVE-2009-1439: Buffer overflow in fs/cifs/connect.c in CIFS in the Linux kernel 2.6.29 and earlier allows remote attackers to cause a denial of service (crash) or potential code execution via a long nativeFileSystem field in a Tree Connect response to an SMB mount request. This requires that kernel can be made to mount a 'cifs' filesystem from a malicious CIFS server. CVE-2009-1337: The exit_notify function in kernel/exit.c in the Linux kernel did not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application. CVE-2009-0859: The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program. (SUSE is enabling CONFIG_SHMEM, so is by default not affected, the fix is just for completeness). CVE-2009-1265: Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel might allow attackers to obtain sensitive information via a large length value, which causes 'garbage' memory to be sent. CVE-2009-0028: The clone system call in the Linux kernel allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit.

CVE-2009-0065: Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID. CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c in the Linux kernel might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call. CVE-2008-4554: The do_splice_from function in fs/splice.c in the Linux kernel does not reject file descriptors that have the O_APPEND flag set, which allows local users to bypass append mode and make arbitrary changes to other locations in the file.

CVE-2009-1337: The exit_notify function in kernel/exit.c in the Linux kernel did not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application. CVE-2009-0859: The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program. (SUSE is enabling CONFIG_SHMEM, so is by default not affected, the fix is just for completeness). CVE-2009-1242: The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel on the i386 platform allows guest OS users to cause a denial of service (OOPS) by setting the EFER_LME (aka 'Long mode enable') bit in the Extended Feature Enable Register (EFER) model-specific register, which is specific to the x86_64 platform. CVE-2009-1265: Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel might allow attackers to obtain sensitive information via a large length value, which causes 'garbage' memory to be sent. CVE-2009-0028: The clone system call in the Linux kernel allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit. CVE-2009-0675: The skfp_ioctl function in drivers/net/skfp/skfddi.c in the Linux kernel permits SKFP_CLR_STATS requests only when the CAP_NET_ADMIN capability is absent, instead of when this capability is present, which allows local users to reset the driver statistics, related to an 'inverted logic' issue. CVE-2009-0676: The sock_getsockopt function in net/core/sock.c in the Linux kernel does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request. CVE-2009-0322: drivers/firmware/dell_rbu.c in the Linux kernel allows local users to cause a denial of service (system crash) via a read system call that specifies zero bytes from the (1) image_type or (2) packet_size file in /sys/devices/platform/dell_rbu/. CVE-2009-0269: fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index. CVE-2009-0065: Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID. Some other non-security bugs were fixed, please see the RPM changelog.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_11_1_KERNEL-090401.NASL
    description This Linux kernel update for openSUSE 11.1 fixes lots of bugs and some security issues. The kernel was also updated to the 2.6.27.21 stable release. CVE-2009-1072: nfsd in the Linux kernel does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option. CVE-2009-0676: The sock_getsockopt function in net/core/sock.c in the Linux kernel does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request. The fix for this was incomplete. CVE-2009-0835: The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod.

    title openSUSE Security Update : kernel (kernel-733)
  • NASL family Ubuntu Local Security Checks
    NASL id UBUNTU_USN-751-1.NASL
    description NFS did not correctly handle races between fcntl and interrupts. A local attacker on an NFS mount could consume unlimited kernel memory, leading to a denial of service. Ubuntu 8.10 was not affected. (CVE-2008-4307) Sparc syscalls did not correctly check mmap regions. A local attacker could cause a system panic, leading to a denial of service. Ubuntu 8.10 was not affected. (CVE-2008-6107) In certain situations, cloned processes were able to send signals to parent processes, crossing privilege boundaries. A local attacker could send arbitrary signals to parent processes, leading to a denial of service. (CVE-2009-0028) The kernel keyring did not free memory correctly. A local attacker could consume unlimited kernel memory, leading to a denial of service. (CVE-2009-0031) The SCTP stack did not correctly validate FORWARD-TSN packets. A remote attacker could send specially crafted SCTP traffic causing a system crash, leading to a denial of service. (CVE-2009-0065) The eCryptfs filesystem did not correctly handle certain VFS return codes. A local attacker with write-access to an eCryptfs filesystem could cause a system crash, leading to a denial of service. (CVE-2009-0269) The Dell platform device did not correctly validate user parameters. A local attacker could perform specially crafted reads to crash the system, leading to a denial of service. (CVE-2009-0322) The page fault handler could consume stack memory. A local attacker could exploit this to crash the system or gain root privileges with a Kprobe registered. Only Ubuntu 8.10 was affected. (CVE-2009-0605) Network interfaces statistics for the SysKonnect FDDI driver did not check capabilities. A local user could reset statistics, potentially interfering with packet accounting systems. (CVE-2009-0675) The getsockopt function did not correctly clear certain parameters. A local attacker could read leaked kernel memory, leading to a loss of privacy. (CVE-2009-0676) The ext4 filesystem did not correctly clear group descriptors when resizing. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2009-0745) The ext4 filesystem did not correctly validate certain fields. A local attacker could mount a malicious ext4 filesystem, causing a system crash, leading to a denial of service. (CVE-2009-0746, CVE-2009-0747, CVE-2009-0748) The syscall interface did not correctly validate parameters when crossing the 64-bit/32-bit boundary. A local attacker could bypass certain syscall restricts via crafted syscalls. (CVE-2009-0834, CVE-2009-0835) The shared memory subsystem did not correctly handle certain shmctl calls when CONFIG_SHMEM was disabled. Ubuntu kernels were not vulnerable, since CONFIG_SHMEM is enabled by default. (CVE-2009-0859) The virtual consoles did not correctly handle certain UTF-8 sequences. A local attacker on the physical console could exploit this to cause a system crash, leading to a denial of service. (CVE-2009-1046). 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.
