ID CVE-2008-4576
Summary sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.

CWE CWE-287
CAPEC
  • Authentication Abuse
    An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker. This attack may exploit assumptions made by the target's authentication procedures, such as assumptions regarding trust relationships or assumptions regarding the generation of secret values. This attack differs from Authentication Bypass attacks in that Authentication Abuse allows the attacker to be certified as a valid user through illegitimate means, while Authentication Bypass allows the user to access protected material without ever being certified as an authenticated user. This attack does not rely on prior sessions established by successfully authenticating users, as relied upon for the "Exploitation of Session Variables, Resource IDs and other Trusted Credentials" attack patterns.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Utilizing REST's Trust in the System Resource to Register Man in the Middle
    This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to place man in the middle once SSL is terminated. Rest applications premise is that they leverage existing infrastructure to deliver web services functionality. An example of this is a Rest application that uses HTTP Get methods and receives a HTTP response with an XML document. These Rest style web services are deployed on existing infrastructure such as Apache and IIS web servers with no SOAP stack required. Unfortunately from a security standpoint, there frequently is no interoperable identity security mechanism deployed, so Rest developers often fall back to SSL to deliver security. In large data centers, SSL is typically terminated at the edge of the network - at the firewall, load balancer, or router. Once the SSL is terminated the HTTP request is in the clear (unless developers have hashed or encrypted the values, but this is rare). The attacker can utilize a sniffer such as Wireshark to snapshot the credentials, such as username and password that are passed in the clear once SSL is terminated. Once the attacker gathers these credentials, they can submit requests to the web service provider just as authorized user do. There is not typically an authentication on the client side, beyond what is passed in the request itself so once this is compromised, then this is generally sufficient to compromise the service's authentication scheme.
  • Man in the Middle Attack
    This type of attack targets the communication between two components (typically client and server). The attacker places himself in the communication channel between the two components. Whenever one component attempts to communicate with the other (data flow, authentication challenges, etc.), the data first goes to the attacker, who has the opportunity to observe or alter it, and it is then passed on to the other component as if it was never intercepted. This interposition is transparent leaving the two compromised components unaware of the potential corruption or leakage of their communications. The potential for Man-in-the-Middle attacks yields an implicit lack of trust in communication or identify between two components.

    description It was discovered that the Xen hypervisor block driver did not correctly validate requests. A user with root privileges in a guest OS could make a malicious IO request with a large number of blocks that would crash the host OS, leading to a denial of service. This only affected Ubuntu 7.10. (CVE-2007-5498) It was discovered the the i915 video driver did not correctly validate memory addresses. A local attacker could exploit this to remap memory that could cause a system crash, leading to a denial of service. This issue did not affect Ubuntu 6.06 and was previous fixed for Ubuntu 7.10 and 8.04 in USN-659-1. Ubuntu 8.10 has now been corrected as well. (CVE-2008-3831) David Watson discovered that the kernel did not correctly strip permissions when creating files in setgid directories. A local user could exploit this to gain additional group privileges. This issue only affected Ubuntu 6.06. (CVE-2008-4210) Olaf Kirch and Miklos Szeredi discovered that the Linux kernel did not correctly reject the 'append' flag when handling file splice requests. A local attacker could bypass append mode and make changes to arbitrary locations in a file. This issue only affected Ubuntu 7.10 and 8.04. (CVE-2008-4554) It was discovered that the SCTP stack did not correctly handle INIT-ACK. A remote user could exploit this by sending specially crafted SCTP traffic which would trigger a crash in the system, leading to a denial of service. This issue did not affect Ubuntu 8.10. (CVE-2008-4576) It was discovered that the SCTP stack did not correctly handle bad packet lengths. A remote user could exploit this by sending specially crafted SCTP traffic which would trigger a crash in the system, leading to a denial of service. This issue did not affect Ubuntu 8.10. (CVE-2008-4618) Eric Sesterhenn discovered multiple flaws in the HFS+ filesystem. If a local user or automated system were tricked into mounting a malicious HFS+ filesystem, the system could crash, leading to a denial of service. (CVE-2008-4933, CVE-2008-4934, CVE-2008-5025) It was discovered that the Unix Socket handler did not correctly process the SCM_RIGHTS message. A local attacker could make a malicious socket request that would crash the system, leading to a denial of service. (CVE-2008-5029) It was discovered that the driver for simple i2c audio interfaces did not correctly validate certain function pointers. A local user could exploit this to gain root privileges or crash the system, leading to a denial of service. (CVE-2008-5033). 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 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. The kernel packages contain the Linux kernel, the core of any Linux operating system. * Olaf Kirch reported a flaw in the i915 kernel driver. This flaw could, potentially, lead to local privilege escalation. Note: the flaw only affects systems based on the Intel G33 Express Chipset and newer. (CVE-2008-3831, Important) * Miklos Szeredi reported a missing check for files opened with O_APPEND in the sys_splice(). This could allow a local, unprivileged user to bypass the append-only file restrictions. (CVE-2008-4554, Important) * a deficiency was found in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. This could lead to a possible denial of service if one end of a SCTP connection did not support the AUTH extension. (CVE-2008-4576, Important) In addition, these updated packages fix the following bugs : * on Itanium(r) systems, when a multithreaded program was traced using the command 'strace -f', messages such as PANIC: attached pid 10740 exited PANIC: handle_group_exit: 10740 leader 10721 ... will be displayed, and after which the trace would stop. With these updated packages, 'strace -f' command no longer results in these error messages, and strace terminates normally after tracing all threads. * on big-endian systems such as PowerPC, the getsockopt() function incorrectly returned 0 depending on the parameters passed to it when the time to live (TTL) value equaled 255. * when using an NFSv4 file system, accessing the same file with two separate processes simultaneously resulted in the NFS client process becoming unresponsive. * on AMD64 and Intel(r) 64 hypervisor-enabled systems, when a syscall correctly returned '-1' in code compiled on Red Hat Enterprise Linux 5, the same code, when run with the strace utility, would incorrectly return an invalid return value. This has been fixed: on AMD64 and Intel(r) 64 hypervisor-enabled systems, syscalls in compiled code return the same, correct values as syscalls run with strace. * on the Itanium(r) architecture, fully-virtualized guest domains created using more than 64 GB of memory caused other guest domains not to receive interrupts. This caused soft lockups on other guests. All guest domains are now able to receive interrupts regardless of their allotted memory. * when user-space used SIGIO notification, which was not disabled before closing a file descriptor and was then re-enabled in a different process, an attempt by the kernel to dereference a stale pointer led to a kernel crash. With this fix, such a situation no longer causes a kernel crash. * modifications to certain pages made through a memory-mapped region could have been lost in cases when the NFS client needed to invalidate the page cache for that particular memory-mapped file. * fully-virtualized Windows(r) guests became unresponsive due to the vIOSAPIC component being multiprocessor-unsafe. With this fix, vIOSAPIC is multiprocessor-safe and Windows guests do not become unresponsive. * on certain systems, keyboard controllers could not withstand continuous requests to switch keyboard LEDs on or off. This resulted in some or all key presses not being registered by the system. * on the Itanium(r) architecture, setting the 'vm.nr_hugepages' sysctl parameter caused a kernel stack overflow resulting in a kernel panic, and possibly stack corruption. With this fix, setting vm.nr_hugepages works correctly. * hugepages allow the Linux kernel to utilize the multiple page size capabilities of modern hardware architectures. In certain configurations, systems with large amounts of memory could fail to allocate most of this memory for hugepages even if it was free. This could result, for example, in database restart failures. Users should upgrade to these updated packages, which contain backported patches to correct these issues.

(CVE-2008-4576, Important) In addition, these updated packages fix the following bugs : - on Itanium® systems, when a multithreaded program was traced using the command 'strace -f', messages similar to the following ones were displayed, after which the trace would stop : PANIC: attached pid 10740 exited PANIC: handle_group_exit: 10740 leader 10721 PANIC: attached pid 10739 exited PANIC: handle_group_exit: 10739 leader 10721 ... In these updated packages, tracing a multithreaded program using the 'strace -f' command no longer results in these error messages, and strace terminates normally after tracing all threads. - on big-endian systems such as PowerPC, the getsockopt() function incorrectly returned 0 depending on the parameters passed to it when the time to live (TTL) value equaled 255. - when using an NFSv4 file system, accessing the same file with two separate processes simultaneously resulted in the NFS client process becoming unresponsive. - on AMD64 and Intel® 64 hypervisor-enabled systems, in cases in which a syscall correctly returned '-1' in code compiled on Red Hat Enterprise Linux 5, the same code, when run with the strace utility, would incorrectly return an invalid return value. This has been fixed so that on AMD64 and Intel® 64 hypervisor-enabled systems, syscalls in compiled code return the same, correct values as syscalls do when run with strace. - on the Itanium® architecture, fully-virtualized guest domains which were created using more than 64 GB of memory caused other guest domains not to receive interrupts, which caused a soft lockup on other guests. All guest domains are now able to receive interrupts regardless of their allotted memory. - when user-space used SIGIO notification, which wasn't disabled before closing a file descriptor, and was then re-enabled in a different process, an attempt by the kernel to dereference a stale pointer led to a kernel crash. With this fix, such a situation no longer causes a kernel crash. - modifications to certain pages made through a memory-mapped region could have been lost in cases when the NFS client needed to invalidate the page cache for that particular memory-mapped file. - fully-virtualized Windows guests became unresponsive due to the vIOSAPIC component being multiprocessor-unsafe. With this fix, vIOSAPIC is multiprocessor-safe and Windows guests do not become unresponsive. - on certain systems, keyboard controllers were not able to withstand a continuous flow of requests to switch keyboard LEDs on or off, which resulted in some or all key presses not being registered by the system. - on the Itanium® architecture, setting the 'vm.nr_hugepages' sysctl parameter caused a kernel stack overflow resulting in a kernel panic, and possibly stack corruption. With this fix, setting vm.nr_hugepages works correctly. - hugepages allow the Linux kernel to utilize the multiple page size capabilities of modern hardware architectures. In certain configurations, systems with large amounts of memory could fail to allocate most of memory for hugepages even if it was free, which could have resulted, for example, in database restart failures.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_KERNEL-5751.NASL
    description This 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.

CVE-2008-4410 The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes write_idt_entry where write_ldt_entry was intended, which allows local users to cause a denial of service (persistent application failure) via crafted function calls, related to the Java Runtime Environment (JRE) experiencing improper LDT selector state, a different vulnerability than CVE-2008-3247. CVE-2008-3525 The sbni_ioctl function in drivers/net/wan/sbni.c in the wan subsystem in the Linux kernel 2.6.26.3 does not check for the CAP_NET_ADMIN capability before processing a (1) SIOCDEVRESINSTATS, (2) SIOCDEVSHWSTATE, (3) SIOCDEVENSLAVE, or (4) SIOCDEVEMANSIPATE ioctl request, which allows local users to bypass intended capability restrictions. CVE-2008-4554 The do_splice_from function in fs/splice.c in the Linux kernel before 2.6.27 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-2008-4576 sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.

    description Several 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-2008-3528 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-2008-4618 Wei Yongjun reported an issue in the SCTP subsystem that may allow remote users to cause a local DoS by triggering a kernel panic. - 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-2008-5134 Johannes Berg reported a remote DoS issue in the libertas wireless driver, which can be triggered by a specially crafted beacon/probe response. - 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.

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.

    title openSUSE 10 Security Update : kernel (kernel-5700)
  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-1687.NASL
    description Several 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.

description sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.
