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 update fixes various security issues and some bugs in the SUSE Linux Enterprise 9 kernel. - The collect_rx_frame function in drivers/isdn/hisax/hfc_usb.c in the Linux kernel allows attackers to have an unspecified impact via a crafted HDLC packet that arrives over ISDN and triggers a buffer under-read. (CVE-2009-4005) - Array index error in the gdth_read_event function in drivers/scsi/gdth.c in the Linux kernel allows local users to cause a denial of service or possibly gain privileges via a negative event index in an IOCTL request. (CVE-2009-3080) - Missing CAP_NET_ADMIN checks in the ebtables netfilter code might have allowed local attackers to modify bridge firewall settings. (CVE-2010-0007) - drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload. (CVE-2009-4536) - The dbg_lvl file for the megaraid_sas driver in the Linux kernel has world-writable permissions, which allows local users to change the (1) behavior and (2) logging level of the driver by modifying this file. (CVE-2009-3889) - The z90crypt_unlocked_ioctl function in the z90crypt driver in the Linux kernel does not perform a capability check for the Z90QUIESCE operation, which allows local users to leverage euid 0 privileges to force a driver outage. (CVE-2009-1883) - Memory leak in the appletalk subsystem in the Linux kernel, when the appletalk and ipddp modules are loaded but the ipddp'N' device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams. (CVE-2009-2903) - net/1/af_unix.c in the Linux kernel allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket. (CVE-2009-3621) - The ATI Rage 128 (aka r128) driver in the Linux kernel does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls.

    title SuSE9 Security Update : the Linux kernel (YOU Patch Number 12578)
  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2009-1438.NASL
    description Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) * it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) * Solar Designer reported a missing capability check in the z90crypt driver in the Linux kernel. This missing check could allow a local user with an effective user ID (euid) of 0 to bypass intended capability restrictions. (CVE-2009-1883, Moderate) * a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate) This update also fixes the following bugs : * the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#517964) * the Emulex LPFC driver has been updated to version 8.0.16.47, which fixes a memory leak that caused memory allocation failures and system hangs. (BZ#513192) * an error in the MPT Fusion driver makefile caused CSMI ioctls to not work with Serial Attached SCSI devices. (BZ#516184) * this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer deference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#517904) * time-outs resulted in I/O errors being logged to '/var/log/messages' when running 'mt erase' on tape drives using certain LSI MegaRAID SAS adapters, preventing the command from completing. The megaraid_sas driver's timeout value is now set to the OS layer value. (BZ#517965) * a locking issue caused the qla2xxx ioctl module to hang after encountering errors. This locking issue has been corrected. This ioctl module is used by the QLogic SAN management tools, such as SANsurfer and scli. (BZ#519428) * when a RAID 1 array that uses the mptscsi driver and the LSI 1030 controller became degraded, the whole array was detected as being offline, which could cause kernel panics at boot or data loss. (BZ#517295) * on 32-bit architectures, if a file was held open and frequently written for more than 25 days, it was possible that the kernel would stop flushing those writes to storage. (BZ#515255) * a memory allocation bug in ib_mthca prevented the driver from loading if it was loaded with large values for the 'num_mpt=' and 'num_mtt=' options. (BZ#518707) * with this update, get_random_int() is more random and no longer uses a common seed value, reducing the possibility of predicting the values returned. (BZ#519692) * a bug in __ptrace_unlink() caused it to create deadlocked and unkillable processes. (BZ#519446) * previously, multiple threads using the fcntl() F_SETLK command to synchronize file access caused a deadlock in posix_locks_deadlock(). This could cause a system hang. (BZ#519429) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
