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 Multiple vulnerabilities in the Linux 2.6 kernel have been discovered and corrected in this update: The kernel on x86_64 platforms does not use a guard page for the 47-bit address page to protect against an AMD K8 bug which allows a local user to cause a DoS (CVE-2005-1764). The KEYCTL_JOIN_SESSION_KEYRING operation in versions prior to 2.6.12.5 contains an error path that does not properly release the session management semaphore, which allows local users or remote attackers to cause a DoS (semaphore hang) via a new session keyring with an empty name string, a long name string, the key quota reached, or ENOMEM (CVE-2005-2098). Kernels prior to 2.6.12.5 do not properly destroy a keyring that is not instantiated properly, allowing a local user or remote attacker to cause a DoS (oops) via a keyring with a payload that is not empty (CVE-2005-2099). An array index overflow in the xfrm_sk_policy_insert function in xfrm_user.c allows local users to cause a DoS (oops or deadlock) and possibly execute arbitrary code (CVE-2005-2456). The zisofs driver in versions prior to 2.6.12.5 allows local users and remove attackers to cause a DoS (crash) via a crafted compressed ISO filesystem (CVE-2005-2457). inflate.c in the zlib routines in versions prior to 2.6.12.5 allow remove attackers to cause a DoS (crash) via a compressed file with 'improper tables' (CVE-2005-2458). The huft_build function in inflate.c in the zlib routines in versions prior to 2.6.12.5 returns the wrong value, allowing remote attackers to cause a DoS (crash) via a certain compressed file that leads to a NULL pointer dereference (CVE-2005-2459). A stack-based buffer overflow in the sendmsg function call in versions prior to 2.6.13.1 allow local users to execute arbitrary code by calling sendmsg and modifying the message contents in another thread (CVE-2005-2490). The raw_sendmsg function in versions prior to 2.6.13.1 allow local users to cause a DoS (change hardware state) or read from arbitrary memory via crafted input (CVE-2005-2492). A memory leak in the seq_file implementation in the SCSI procfs interface (sg.c) in 2.6.13 and earlier allows a local user to cause a DoS (memory consumption) via certain repeated reads from /proc/scsi/gs/devices file which is not properly handled when the next() interator returns NULL or an error (CVE-2005-2800). The ipt_recent module in versions prior to 2.6.12 when running on 64bit processors allows remote attackers to cause a DoS (kernel panic) via certain attacks such as SSH brute force (CVE-2005-2872). The ipt_recent module in versions prior to 2.6.12 does not properly perform certain tests when the jiffies value is greater than LONG_MAX, which can cause ipt_recent netfilter rules to block too early (CVE-2005-2873). Multiple vulnerabilities in versions prior to 2.6.13.2 allow local users to cause a DoS (oops from NULL dereference) via fput in a 32bit ioctl on 64-bit x86 systems or sockfd_put in the 32-bit routing_ioctl function on 64-bit systems (CVE-2005-3044). The sys_set_mempolicy function in mempolicy.c allows local users to cause a DoS via a negative first argument (CVE-2005-3053). Versions 2.6.8 to 2.6.14-rc2 allow local users to cause a DoS (oops) via a userspace process that issues a USB Request Block (URB) to a USB device and terminates before the URB is finished, which leads to a stale pointer reference (CVE-2005-3055). drm.c in version 2.6.13 and earlier creates a debug file in sysfs with world-readable and world-writable permissions, allowing local users to enable DRM debugging and obtain sensitive information (CVE-2005-3179). The Orinoco driver in 2.6.13 and earlier does not properly clear memory from a previously used packet whose length is increased, allowing remote attackers to obtain sensitive information (CVE-2005-3180). Kernels 2.6.13 and earlier, when CONFIG_AUDITSYSCALL is enabled, use an incorrect function to free names_cache memory, preventing the memory from being tracked by AUDITSYSCALL code and leading to a memory leak (CVE-2005-3181). The VT implementation in version 2.6.12 allows local users to use certain IOCTLs on terminals of other users and gain privileges (CVE-2005-3257). Exec does not properly clear posix-timers in multi-threaded environments, which result in a resource leak and could allow a large number of multiple local users to cause a DoS by using more posix- timers than specified by the quota for a single user (CVE-2005-3271). The rose_rt_ioctl function rose_route.c in versions prior to 2.6.12 does not properly verify the ndigis argument for a new route, allowing an attacker to trigger array out-of-bounds errors with a large number of digipeats (CVE-2005-3273). A race condition in ip_vs_conn_flush in versions prior to 2.6.13, when running on SMP systems, allows local users to cause a DoS (NULL dereference) by causing a connection timer to expire while the connection table is being flushed before the appropriate lock is acquired (CVE-2005-3274). The NAT code in versions prior to 2.6.13 incorrectly declares a variable to be static, allowing remote attackers to cause a DoS (memory corruption) by causing two packets for the same protocol to be NATed at the same time (CVE-2005-3275). The sys_get_thread_area function in process.c in versions prior to 2.6.12.4 and 2.6.13 does not clear a data structure before copying it to userspace, which may allow a user process to obtain sensitive information (CVE-2005-3276). The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels.

    description Rudolf Polzer reported an abuse of the 'loadkeys' command. By redefining one or more keys and tricking another user (like root) into logging in on a text console and typing something that involves the redefined keys, a local user could cause execution of arbitrary commands with the privileges of the target user. The updated kernel restricts the usage of 'loadkeys' to root. (CVE-2005-3257) The ptrace() system call did not correctly check whether a process tried to attach to itself. A local attacker could exploit this to cause a kernel crash. (CVE-2005-3783) A Denial of Service vulnerability was found in the handler that automatically cleans up and terminates child processes that are not correctly handled by their parent process ('auto-reaper'). The check did not correctly handle processes which were currently traced by another process. A local attacker could exploit this to cause a kernel crash. (CVE-2005-3784) A locking problem was discovered in the POSIX timer cleanup handling on process exit. A local attacker could exploit this to cause the machine to hang (Denial of Service). This flaw only affects multiprocessor (SMP) systems. (CVE-2005-3805) A Denial of Service vulnerability was discovered in the IPv6 flowlabel handling code. By invoking setsockopt(IPV6_FLOWLABEL_MGR) in a special way, a local attacker could cause memory corruption which eventually led to a kernel crash. (CVE-2005-3806) A memory leak was discovered in the VFS lease handling. These operations are commonly executed by the Samba server, which led to steady memory exhaustion. By repeatedly triggering the affected operations in quick succession, a local attacker could exploit this to drain all memory, which leads to a Denial of Service. (CVE-2005-3807) An integer overflow was discovered in the invalidate_inode_pages2_range() function. By issuing 64-bit mmap calls on a 32 bit system, a local user could exploit this to crash the machine, thereby causing Denial of Service. This flaw does not affect the amd64 platform, and does only affect Ubuntu 5.10. (CVE-2005-3808) Ollie Wild discovered a memory leak in the icmp_push_reply() function. By sending a large amount of specially crafted packets, a remote attacker could exploit this to drain all memory, which eventually leads to a Denial of Service. (CVE-2005-3848) Chris Wrigth found a Denial of Service vulnerability in the time_out_leases() function. By allocating a large number of VFS file lock leases and having them timeout at the same time, a large number of 'printk' debugging statements was generated at the same time, which could exhaust kernel memory. (CVE-2005-3857) Patrick McHardy discovered a memory leak in the ip6_input_finish() function. A remote attacker could exploit this by sending specially crafted IPv6 packets, which would eventually drain all available kernel memory, thus causing a Denial of Service. (CVE-2005-3858). 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.

    description Multiple vulnerabilities in the Linux 2.6 kernel have been discovered and corrected in this update : An integer overflow in vc_resize (CVE-2004-1333). A race condition in the sysfs_read_file and sysfs_write_file functions in 2.6.10 and earlier allows local users to read kernel memory and cause a DoS (crash) via large offsets in sysfs files (CVE-2004-2302). An integer signedness error in scsi_ioctl.c (CVE-2005-0180). Netfilter allows a local user to cause a DoS (memory consumption) via certain packet fragments that are reassembled twice, which causes a data structure to be allocated twice (CVE-2005-0210). A DoS in pkt_ioctl in pktcdvc.c (CVE-2005-1589).

The kernel does not properly restrict socket policy access to users with the CAP_NET_ADMIN capability, which could allow local users to conduct unauthorized activities via ipv4/ip_sockglue.c and ipv6/ipv6_sockglue.c (CVE-2005-2555). A memory leak in the seq_file implementation in the SCSI procfs interface (sg.c) in 2.6.13 and earlier allows a local user to cause a DoS (memory consumption) via certain repeated reads from /proc/scsi/gs/devices file which is not properly handled when the next() interator returns NULL or an error (CVE-2005-2800). xattr.c in the ext2 and ext3 file system code does not properly compare the name_index fields when sharing xattr blocks which could prevent ACLs from being applied (CVE-2005-2801).

    description The original update lacked recompiled ALSA modules against the new kernel ABI. Furthermore, kernel-latest-2.4-sparc now correctly depends on the updated packages. For completeness we're providing the original problem description : Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2004-0887 Martin Schwidefsky discovered that the privileged instruction SACF (Set Address Space Control Fast) on the S/390 platform is not handled properly, allowing for a local user to gain root privileges. - CVE-2004-1058 A race condition allows for a local user to read the environment variables of another process that is still spawning through /proc/.../cmdline. - CVE-2004-2607 A numeric casting discrepancy in sdla_xfer allows local users to read portions of kernel memory via a large len argument which is received as an int but cast to a short, preventing read loop from filling a buffer. - CVE-2005-0449 An error in the skb_checksum_help() function from the netfilter framework has been discovered that allows the bypass of packet filter rules or a denial of service attack. - CVE-2005-1761 A vulnerability in the ptrace subsystem of the IA-64 architecture can allow local attackers to overwrite kernel memory and crash the kernel. - CVE-2005-2457 Tim Yamin discovered that insufficient input validation in the compressed ISO file system (zisofs) allows a denial of service attack through maliciously crafted ISO images. - CVE-2005-2555 Herbert Xu discovered that the setsockopt() function was not restricted to users/processes with the CAP_NET_ADMIN capability. This allows attackers to manipulate IPSEC policies or initiate a denial of service attack. - CVE-2005-2709 Al Viro discovered a race condition in the /proc handling of network devices. A (local) attacker could exploit the stale reference after interface shutdown to cause a denial of service or possibly execute code in kernel mode. - CVE-2005-2973 Tetsuo Handa discovered that the udp_v6_get_port() function from the IPv6 code can be forced into an endless loop, which allows a denial of service attack. - CVE-2005-3257 Rudolf Polzer discovered that the kernel improperly restricts access to the KDSKBSENT ioctl, which can possibly lead to privilege escalation. - CVE-2005-3783 The ptrace code using CLONE_THREAD didn't use the thread group ID to determine whether the caller is attaching to itself, which allows a denial of service attack. - CVE-2005-3806 Yen Zheng discovered that the IPv6 flow label code modified an incorrect variable, which could lead to memory corruption and denial of service. - CVE-2005-3848 Ollie Wild discovered a memory leak in the icmp_push_reply() function, which allows denial of service through memory consumption. - CVE-2005-3857 Chris Wright discovered that excessive allocation of broken file lock leases in the VFS layer can exhaust memory and fill up the system logging, which allows denial of service. - CVE-2005-3858 Patrick McHardy discovered a memory leak in the ip6_input_finish() function from the IPv6 code, which allows denial of service. - CVE-2005-4618 Yi Ying discovered that sysctl does not properly enforce the size of a buffer, which allows a denial of service attack.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2004-1017 Multiple overflows exist in the io_edgeport driver which might be usable as a denial of service attack vector. - CVE-2005-0124 Bryan Fulton reported a bounds checking bug in the coda_pioctl function which may allow local users to execute arbitrary code or trigger a denial of service attack. - CVE-2005-0449 An error in the skb_checksum_help() function from the netfilter framework has been discovered that allows the bypass of packet filter rules or a denial of service attack. - CVE-2005-2457 Tim Yamin discovered that insufficient input validation in the zisofs driver for compressed ISO file systems allows a denial of service attack through maliciously crafted ISO images. - CVE-2005-2490 A buffer overflow in the sendmsg() function allows local users to execute arbitrary code. - CVE-2005-2555 Herbert Xu discovered that the setsockopt() function was not restricted to users/processes with the CAP_NET_ADMIN capability. This allows attackers to manipulate IPSEC policies or initiate a denial of service attack. - CVE-2005-2709 Al Viro discovered a race condition in the /proc handling of network devices. A (local) attacker could exploit the stale reference after interface shutdown to cause a denial of service or possibly execute code in kernel mode. - CVE-2005-2800 Jan Blunck discovered that repeated failed reads of /proc/scsi/sg/devices leak memory, which allows a denial of service attack. - CVE-2005-2973 Tetsuo Handa discovered that the udp_v6_get_port() function from the IPv6 code can be forced into an endless loop, which allows a denial of service attack. - CVE-2005-3044 Vasiliy Averin discovered that the reference counters from sockfd_put() and fput() can be forced into overlapping, which allows a denial of service attack through a NULL pointer dereference. - CVE-2005-3053 Eric Dumazet discovered that the set_mempolicy() system call accepts a negative value for its first argument, which triggers a BUG() assert. This allows a denial of service attack. - CVE-2005-3055 Harald Welte discovered that if a process issues a USB Request Block (URB) to a device and terminates before the URB completes, a stale pointer would be dereferenced. This could be used to trigger a denial of service attack. - CVE-2005-3180 Pavel Roskin discovered that the driver for Orinoco wireless cards clears its buffers insufficiently. This could leak sensitive information into user space. - CVE-2005-3181 Robert Derr discovered that the audit subsystem uses an incorrect function to free memory, which allows a denial of service attack. - CVE-2005-3257 Rudolf Polzer discovered that the kernel improperly restricts access to the KDSKBSENT ioctl, which can possibly lead to privilege escalation. - CVE-2005-3356 Doug Chapman discovered that the mq_open syscall can be tricked into decrementing an internal counter twice, which allows a denial of service attack through a kernel panic. - CVE-2005-3358 Doug Chapman discovered that passing a zero bitmask to the set_mempolicy() system call leads to a kernel panic, which allows a denial of service attack. - CVE-2005-3783 The ptrace code using CLONE_THREAD didn't use the thread group ID to determine whether the caller is attaching to itself, which allows a denial of service attack. - CVE-2005-3784 The auto-reaping of child processes functionality included ptraced-attached processes, which allows denial of service through dangling references. - CVE-2005-3806 Yen Zheng discovered that the IPv6 flow label code modified an incorrect variable, which could lead to memory corruption and denial of service. - CVE-2005-3847 It was discovered that a threaded real-time process, which is currently dumping core can be forced into a dead-lock situation by sending it a SIGKILL signal, which allows a denial of service attack. - CVE-2005-3848 Ollie Wild discovered a memory leak in the icmp_push_reply() function, which allows denial of service through memory consumption. - CVE-2005-3857 Chris Wright discovered that excessive allocation of broken file lock leases in the VFS layer can exhaust memory and fill up the system logging, which allows denial of service. - CVE-2005-3858 Patrick McHardy discovered a memory leak in the ip6_input_finish() function from the IPv6 code, which allows denial of service. - CVE-2005-4605 Karl Janmar discovered that a signedness error in the procfs code can be exploited to read kernel memory, which may disclose sensitive information. - CVE-2005-4618 Yi Ying discovered that sysctl does not properly enforce the size of a buffer, which allows a denial of service attack. - CVE-2006-0095 Stefan Rompf discovered that dm_crypt does not clear an internal struct before freeing it, which might disclose sensitive information. - CVE-2006-0096 It was discovered that the SDLA driver's capability checks were too lax for firmware upgrades. - CVE-2006-0482 Ludovic Courtes discovered that get_compat_timespec() performs insufficient input sanitizing, which allows a local denial of service attack. - CVE-2006-1066 It was discovered that ptrace() on the ia64 architecture allows a local denial of service attack, when preemption is enabled.
