Vulnerabilities > CVE-2009-1337 - Permissions, Privileges, and Access Controls vulnerability in Linux Kernel
Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
The exit_notify function in kernel/exit.c in the Linux kernel before 2.6.30-rc1 does 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.
Vulnerable Configurations
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.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2009-1024.NASL description Updated kernel packages are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 4. This is the eighth regular update. These updated packages fix two security issues, hundreds of bugs, and add numerous enhancements. Space precludes a detailed description of each of these in this advisory. Refer to the Red Hat Enterprise Linux 4.8 Release Notes for information on 22 of the most significant of these changes. For more detailed information on specific bug fixes or enhancements, refer to the Bugzilla numbers associated with this advisory. 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. Security Fixes : * the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) * the Linux kernel implementation of the Network File System (NFS) did not properly initialize the file name limit in the nfs_server data structure. This flaw could possibly lead to a denial of service on a client mounting an NFS share.

NASL family SuSE Local Security Checks NASL id SUSE_11_1_KERNEL-090527.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 2.6.27.23 stable release. Following security issues have been fixed: 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.

The kernel was also updated to the 2.6.27.23 stable release. Following security issues have been fixed: 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. The GCC option -fwrapv has been added to compilation to work around potentially removing integer overflow checks. 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-2009-1242: 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-2009-1360: The __inet6_check_established function in net/ipv6/inet6_hashtables.c in the Linux kernel, when Network Namespace Support (aka NET_NS) is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via vectors involving IPv6 packets. CVE-2009-1192: drivers/char/agp/generic.c in the agp subsystem in the Linux kernel does not zero out pages that may later be available to a user-space process, which allows local users to obtain sensitive information by reading these pages.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2009-1550.NASL description Updated kernel packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise Linux 3. 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. Security fixes : * when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue. (CVE-2008-5029, Important) * the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important) * the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) * a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important) * 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) * missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important) * a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe last seen 2020-06-01 modified 2020-06-02 plugin id 42360 published 2009-11-04 reporter This script is Copyright (C) 2009-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/42360 title RHEL 3 : kernel (RHSA-2009:1550) code #%NASL_MIN_LEVEL 80502 # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Red Hat Security Advisory RHSA-2009:1550.

(BZ#505514) * 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#511185) * a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable.

NASL family Scientific Linux Local Security Checks NASL id SL_20090630_KERNEL_ON_SL4_X.NASL description These updated packages fix the following security issues : - the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) - the Linux kernel implementation of the Network File System (NFS) did not properly initialize the file name limit in the nfs_server data structure. This flaw could possibly lead to a denial of service on a client mounting an NFS share. (CVE-2009-1336, Moderate) - a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service. (CVE-2009-1385, Important) - the Linux kernel Network File System daemon (nfsd) implementation did not drop the CAP_MKNOD capability when handling requests from local, unprivileged users. This flaw could possibly lead to an information leak or privilege escalation. (CVE-2009-1072, Moderate) - Frank Filz reported the NFSv4 client was missing a file permission check for the execute bit in some situations. This could allow local, unprivileged users to run non-executable files on NFSv4 mounted file systems. (CVE-2009-1630, Moderate) - a missing check was found in the hypervisor_callback() function in the Linux kernel provided by the kernel-xen package. This could cause a denial of service of a 32-bit guest if an application running in that guest accesses a certain memory location in the kernel. (CVE-2009-1758, Moderate) - a flaw was found in the AGPGART driver. The agp_generic_alloc_page() and agp_generic_alloc_pages() functions did not zero out the memory pages they allocate, which may later be available to user-space processes. This flaw could possibly lead to an information leak. (CVE-2009-1192, Low) These updated packages also fix the following bugs : - last seen 2020-06-01 modified 2020-06-02 plugin id 60609 published 2012-08-01 reporter This script is Copyright (C) 2012-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/60609 title Scientific Linux Security Update : kernel on SL4.x i386/x86_64 NASL family SuSE Local Security Checks NASL id SUSE_11_0_KERNEL-090602.NASL description This kernel update for openSUSE 11.0 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-2009-1630: The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver. 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-2009-1072: nfsd in the Linux kernel did 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.

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. Security fixes : * when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue. (CVE-2008-5029, Important) * the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important) * the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) * a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important) * 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) * missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak.
