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.

"Updated kernel packages that resolve several security issues and fix
various bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

[Updated 12th November 2008] The original packages distributed with
this errata had a bug which prevented the Xen kernel booting on older
hardware. We have updated the packages to correct this bug.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* the Xen implementation did not prevent applications running in a
para-virtualized guest from modifying CR4 TSC. This could cause a
local denial of service. (CVE-2007-5907, Important)

* Tavis Ormandy reported missing boundary checks in the Virtual
Dynamic Shared Objects (vDSO) implementation. This could allow a local
unprivileged user to cause a denial of service or escalate privileges.
(CVE-2008-3527, Important)

* the do_truncate() and generic_file_splice_write() functions did not
clear the setuid and setgid bits. This could allow a local
unprivileged user to obtain access to privileged information.
(CVE-2008-4210, CVE-2008-3833, Important)

* a flaw was found in the Linux kernel splice implementation. This
could cause a local denial of service when there is a certain failure
in the add_to_page_cache_lru() function. (CVE-2008-4302, Important)

* a flaw was found in the Linux kernel when running on AMD64 systems.
During a context switch, EFLAGS were being neither saved nor restored.
This could allow a local unprivileged user to cause a denial of
service. (CVE-2006-5755, Low)

* a flaw was found in the Linux kernel virtual memory implementation.
This could allow a local unprivileged user to cause a denial of
service. (CVE-2008-2372, Low)

* an integer overflow was discovered in the Linux kernel Datagram
Congestion Control Protocol (DCCP) implementation. This could allow a
remote attacker to cause a denial of service. By default, remote DCCP
is blocked by SELinux. (CVE-2008-3276, Low)

In addition, these updated packages fix the following bugs :

* random32() seeding has been improved.

* in a multi-core environment, a race between the QP async
event-handler and the destro_qp() function could occur. This led to
unpredictable results during invalid memory access, which could lead
to a kernel crash.

* a format string was omitted in the call to the request_module()
function.

* a stack overflow caused by an infinite recursion bug in the
binfmt_misc kernel module was corrected.

* the ata_scsi_rbuf_get() and ata_scsi_rbuf_put() functions now check
for scatterlist usage before calling kmap_atomic().

* a sentinel NUL byte was added to the device_write() function to
ensure that lspace.name is NUL-terminated.

* in the character device driver, a range_is_allowed() check was added
to the read_mem() and write_mem() functions. It was possible for an
illegitimate application to bypass these checks, and access /dev/mem
beyond the 1M limit by calling mmap_mem() instead. Also, the
parameters of range_is_allowed() were changed to cleanly handle
greater than 32-bits of physical address on 32-bit architectures.

* some of the newer Nehalem-based systems declare their CPU DSDT
entries as type 'Alias'. During boot, this caused an 'Error attaching
device data' message to be logged.

* the evtchn event channel device lacked locks and memory barriers.
This has led to xenstore becoming unresponsive on the Itanium(r)
architecture.

* sending of gratuitous ARP packets in the Xen frontend network driver
is now delayed until the backend signals that its carrier status has
been processed by the stack.

* on forcedeth devices, whenever setting ethtool parameters for link
speed, the device could stop receiving interrupts.

* the CIFS 'forcedirectio' option did not allow text to be appended to
files.

* the gettimeofday() function returned a backwards time on Intel(r) 64.

* residual-count corrections during UNDERRUN handling were added to
the qla2xxx driver.

* the fix for a small quirk was removed for certain Adaptec
controllers for which it caused problems.

* the 'xm trigger init' command caused a domain panic if a userland
application was running on a guest on the Intel(r) 64 architecture.

Users of kernel should upgrade to these updated packages, which
contain backported patches to correct these issues."

  - the ata_scsi_rbuf_get() and ata_scsi_rbuf_put()
    functions now check for scatterlist usage before calling
    kmap_atomic().

  - a sentinel NUL byte was added to the device_write()
    function to ensure that lspace.name is NUL-terminated.

  - in the character device driver, a range_is_allowed()

"From Red Hat Security Advisory 2008:0957 :

Updated kernel packages that resolve several security issues and fix
various bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

[Updated 12th November 2008] The original packages distributed with
this errata had a bug which prevented the Xen kernel booting on older
hardware. We have updated the packages to correct this bug.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* the Xen implementation did not prevent applications running in a
para-virtualized guest from modifying CR4 TSC. This could cause a
local denial of service. (CVE-2007-5907, Important)

* Tavis Ormandy reported missing boundary checks in the Virtual
Dynamic Shared Objects (vDSO) implementation. This could allow a local
unprivileged user to cause a denial of service or escalate privileges.
(CVE-2008-3527, Important)

* the do_truncate() and generic_file_splice_write() functions did not
clear the setuid and setgid bits. This could allow a local
unprivileged user to obtain access to privileged information.
(CVE-2008-4210, CVE-2008-3833, Important)

* a flaw was found in the Linux kernel splice implementation. This
could cause a local denial of service when there is a certain failure
in the add_to_page_cache_lru() function. (CVE-2008-4302, Important)

* a flaw was found in the Linux kernel when running on AMD64 systems.
During a context switch, EFLAGS were being neither saved nor restored.
This could allow a local unprivileged user to cause a denial of
service. (CVE-2006-5755, Low)

* a flaw was found in the Linux kernel virtual memory implementation.
This could allow a local unprivileged user to cause a denial of
service. (CVE-2008-2372, Low)

* an integer overflow was discovered in the Linux kernel Datagram
Congestion Control Protocol (DCCP) implementation. This could allow a
remote attacker to cause a denial of service. By default, remote DCCP
is blocked by SELinux. (CVE-2008-3276, Low)

In addition, these updated packages fix the following bugs :

* random32() seeding has been improved.

* in a multi-core environment, a race between the QP async
event-handler and the destro_qp() function could occur. This led to
unpredictable results during invalid memory access, which could lead
to a kernel crash.

* a format string was omitted in the call to the request_module()
function.

* a stack overflow caused by an infinite recursion bug in the
binfmt_misc kernel module was corrected.

* the ata_scsi_rbuf_get() and ata_scsi_rbuf_put() functions now check
for scatterlist usage before calling kmap_atomic().

* a sentinel NUL byte was added to the device_write() function to
ensure that lspace.name is NUL-terminated.

* in the character device driver, a range_is_allowed() check was added
to the read_mem() and write_mem() functions. It was possible for an
illegitimate application to bypass these checks, and access /dev/mem
beyond the 1M limit by calling mmap_mem() instead. Also, the
parameters of range_is_allowed() were changed to cleanly handle
greater than 32-bits of physical address on 32-bit architectures.

* some of the newer Nehalem-based systems declare their CPU DSDT
entries as type 'Alias'. During boot, this caused an 'Error attaching
device data' message to be logged.

* the evtchn event channel device lacked locks and memory barriers.
This has led to xenstore becoming unresponsive on the Itanium(r)
architecture.

* sending of gratuitous ARP packets in the Xen frontend network driver
is now delayed until the backend signals that its carrier status has
been processed by the stack.

* on forcedeth devices, whenever setting ethtool parameters for link
speed, the device could stop receiving interrupts.

* the CIFS 'forcedirectio' option did not allow text to be appended to
files.

* the gettimeofday() function returned a backwards time on Intel(r) 64.

* residual-count corrections during UNDERRUN handling were added to
the qla2xxx driver.

* the fix for a small quirk was removed for certain Adaptec
controllers for which it caused problems.

* the 'xm trigger init' command caused a domain panic if a userland
application was running on a guest on the Intel(r) 64 architecture.

Users of kernel should upgrade to these updated packages, which
contain backported patches to correct these issues."

    descriptionThis kernel update fixes various bugs and also several security issues : CVE-2008-4576: Fixed a crash in SCTP INIT-ACK, on mismatch between SCTP AUTH availability. This might be exploited remotely for a denial of service (crash) attack. CVE-2008-3833: The generic_file_splice_write function in fs/splice.c in the Linux kernel does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by splicing into an inode in order to create an executable file in a setgid directory. CVE-2008-4210: fs/open.c in the Linux kernel before 2.6.22 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by creating an executable file in a setgid directory through the (1) truncate or (2) ftruncate function in conjunction with memory-mapped I/O. CVE-2008-4302: fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool. CVE-2008-3528: The ext[234] filesystem code fails to properly handle corrupted data structures. With a mounted filesystem image or partition that have corrupted dir->i_size and dir->i_blocks, a user performing either a read or write operation on the mounted image or partition can lead to a possible denial of service by spamming the logfile. CVE-2007-6716: fs/direct-io.c in the dio subsystem in the Linux kernel did not properly zero out the dio struct, which allows local users to cause a denial of service (OOPS), as demonstrated by a certain fio test. CVE-2008-3525: Added missing capability checks in sbni_ioctl(). CVE-2008-3272: Fixed range checking in the snd_seq OSS ioctl, which could be used to leak information from the kernel. CVE-2008-2931: The do_change_type function in fs/namespace.c did not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint. CVE-2008-2812: Various NULL ptr checks have been added to tty op functions, which might have been used by local attackers to execute code. We think that this affects only devices openable by root, so the impact is limited. CVE-2008-1673: Added range checking in ASN.1 handling for the CIFS and SNMP NAT netfilter modules. CVE-2008-3527: arch/i386/kernel/sysenter.c in the Virtual Dynamic Shared Objects (vDSO) implementation in the Linux kernel before 2.6.21 did not properly check boundaries, which allows local users to gain privileges or cause a denial of service via unspecified vectors, related to the install_special_mapping, syscall, and syscall32_nopage functions.

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2008-3527 Tavis Ormandy reported a local DoS and potential privilege escalation in the Virtual Dynamic Shared Objects (vDSO) implementation. - CVE-2008-3528 Eugene Teo reported a local DoS issue in the ext2 and ext3 filesystems. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that causes the kernel to output error messages in an infinite loop. - CVE-2008-4554 Milos Szeredi reported that the usage of splice() on files opened with O_APPEND allows users to write to the file at arbitrary offsets, enabling a bypass of possible assumed semantics of the O_APPEND flag. - CVE-2008-4576 Vlad Yasevich reported an issue in the SCTP subsystem that may allow remote users to cause a local DoS by triggering a kernel oops. - CVE-2008-4933 Eric Sesterhenn reported a local DoS issue in the hfsplus filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that causes the kernel to overrun a buffer, resulting in a system oops or memory corruption. - CVE-2008-4934 Eric Sesterhenn reported a local DoS issue in the hfsplus filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that results in a kernel oops due to an unchecked return value. - CVE-2008-5025 Eric Sesterhenn reported a local DoS issue in the hfs filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a filesystem with a corrupted catalog name length, resulting in a system oops or memory corruption. - CVE-2008-5029 Andrea Bittau reported a DoS issue in the unix socket subsystem that allows a local user to cause memory corruption, resulting in a kernel panic. - CVE-2008-5079 Hugo Dias reported a DoS condition in the ATM subsystem that can be triggered by a local user by calling the svc_listen function twice on the same socket and reading /proc/net/atm/*vc. - CVE-2008-5182 Al Viro reported race conditions in the inotify subsystem that may allow local users to acquire elevated privileges. - CVE-2008-5300 Dann Frazier reported a DoS condition that allows local users to cause the out of memory handler to kill off privileged processes or trigger soft lockups due to a starvation issue in the unix socket subsystem.
