Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Command Delimiters
    An attack of this type exploits a programs' vulnerabilities that allows an attacker's commands to be concatenated onto a legitimate command with the intent of targeting other resources such as the file system or database. The system that uses a filter or a blacklist input validation, as opposed to whitelist validation is vulnerable to an attacker who predicts delimiters (or combinations of delimiters) not present in the filter or blacklist. As with other injection attacks, the attacker uses the command delimiter payload as an entry point to tunnel through the application and activate additional attacks through SQL queries, shell commands, network scanning, and so on.
  • Flash Parameter Injection
    An attacker injects values to global parameters into a Flash movie embedded in an HTML document. These injected parameters are controlled through arguments in the URL used to access the embedding HTML document. As such, this is a form of HTTP parameter injection, but the abilities granted to the Flash document (such as access to a page's document model, including associated cookies) make this attack more flexible. The injected parameters can allow the attacker to control other objects within the Flash movie as well as full control over the parent document's DOM model.
  • Embedding Scripts in Non-Script Elements
    This attack is a form of Cross-Site Scripting (XSS) where malicious scripts are embedded in elements that are not expected to host scripts such as image tags (<img>), comments in XML documents (< !-CDATA->), etc. These tags may not be subject to the same input validation, output validation, and other content filtering and checking routines, so this can create an opportunity for an attacker to tunnel through the application's elements and launch a XSS attack through other elements. As with all remote attacks, it is important to differentiate the ability to launch an attack (such as probing an internal network for unpatched servers) and the ability of the remote attacker to collect and interpret the output of said attack.

    descriptionSeveral 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-2005-0756 Alexander Nyberg discovered that the ptrace() system call does not properly verify addresses on the amd64 architecture which can be exploited by a local attacker to crash the kernel. - CVE-2005-0757 A problem in the offset handling in the xattr file system code for ext3 has been discovered that may allow users on 64-bit systems that have access to an ext3 filesystem with extended attributes to cause the kernel to crash. - CVE-2005-1762 A vulnerability has been discovered in the ptrace() system call on the amd64 architecture that allows a local attacker to cause the kernel to crash. - CVE-2005-1767 A vulnerability has been discovered in the stack segment fault handler that could allow a local attacker to cause a stack exception that will lead the kernel to crash under certain circumstances. - CVE-2005-1768 Ilja van Sprundel discovered a race condition in the IA32 (x86) compatibility execve() systemcall for amd64 and IA64 that allows local attackers to cause the kernel to panic and possibly execute arbitrary code. - CVE-2005-2456 Balazs Scheidler discovered that a local attacker could call setsockopt() with an invalid xfrm_user policy message which would cause the kernel to write beyond the boundaries of an array and crash. - CVE-2005-2458 Vladimir Volovich discovered a bug in the zlib routines which are also present in the Linux kernel and allows remote attackers to crash the kernel. - CVE-2005-2459 Another vulnerability has been discovered in the zlib routines which are also present in the Linux kernel and allows remote attackers to crash the kernel. - CVE-2005-2553 A NULL pointer dereference in ptrace when tracing a 64-bit executable can cause the kernel to crash. - CVE-2005-2801 Andreas Gruenbacher discovered a bug in the ext2 and ext3 file systems. When data areas are to be shared among two inodes not all information were compared for equality, which could expose wrong ACLs for files. - CVE-2005-2872 Chad Walstrom discovered that the ipt_recent kernel module to stop SSH bruteforce attacks could cause the kernel to crash on 64-bit architectures. - CVE-2005-3275 An error in the NAT code allows remote attackers to cause a denial of service (memory corruption) by causing two packets for the same protocol to be NATed at the same time, which leads to memory corruption.

The Linux kernel handles the basic functions of the operating system.

This is the seventh regular kernel update to Red Hat Enterprise Linux
3.

New features introduced by this update include :

  - addition of the bnx2, dell_rbu, and megaraid_sas device
    drivers - support for multi-core, multi-threaded Intel
    Itanium processors - upgrade of the SATA subsystem to
    include ATAPI and SMART support - optional tuning via
    the new numa_memory_allocator, arp_announce, and
    printk_ratelimit sysctls

There were many bug fixes in various parts of the kernel. The ongoing
effort to resolve these problems has resulted in a marked improvement
in the reliability and scalability of Red Hat Enterprise Linux 3.

There were numerous driver updates and security fixes (elaborated
below). Other key areas affected by fixes in this update include the
networking subsystem, the VM subsystem, NPTL handling, autofs4, the
USB subsystem, CPU enumeration, and 32-bit-exec-mode handling on

The following security bugs were fixed in this update :

  - a flaw in gzip/zlib handling internal to the kernel that
    allowed a local user to cause a denial of service
    (crash) (CVE-2005-2458,low)

  - a flaw in ext3 EA/ACL handling of attribute sharing that
    allowed a local user to gain privileges (CVE-2005-2801,
    moderate)

  - a minor info leak with the get_thread_area() syscall
    that allowed a local user to view uninitialized kernel
    stack data (CVE-2005-3276, low)

Note: The kernel-unsupported package contains various drivers and
modules that are unsupported and therefore might contain security
problems that have not been addressed.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2004-2302 A race condition in the sysfs filesystem allows local users to read kernel memory and cause a denial of service (crash). - CVE-2005-0756 Alexander Nyberg discovered that the ptrace() system call does not properly verify addresses on the amd64 architecture which can be exploited by a local attacker to crash the kernel. - CVE-2005-0757 A problem in the offset handling in the xattr file system code for ext3 has been discovered that may allow users on 64-bit systems that have access to an ext3 filesystem with extended attributes to cause the kernel to crash. - CVE-2005-1265 Chris Wright discovered that the mmap() function could create illegal memory maps that could be exploited by a local user to crash the kernel or potentially execute arbitrary code. - CVE-2005-1761 A vulnerability on the IA-64 architecture can lead local attackers to overwrite kernel memory and crash the kernel. - CVE-2005-1762 A vulnerability has been discovered in the ptrace() system call on the amd64 architecture that allows a local attacker to cause the kernel to crash. - CVE-2005-1763 A buffer overflow in the ptrace system call for 64-bit architectures allows local users to write bytes into arbitrary kernel memory. - CVE-2005-1765 Zou Nan Hai has discovered that a local user could cause the kernel to hang on the amd64 architecture after invoking syscall() with specially crafted arguments. - CVE-2005-1767 A vulnerability has been discovered in the stack segment fault handler that could allow a local attacker to cause a stack exception that will lead the kernel to crash under certain circumstances. - CVE-2005-2456 Balazs Scheidler discovered that a local attacker could call setsockopt() with an invalid xfrm_user policy message which would cause the kernel to write beyond the boundaries of an array and crash. - CVE-2005-2458 Vladimir Volovich discovered a bug in the zlib routines which are also present in the Linux kernel and allows remote attackers to crash the kernel. - CVE-2005-2459 Another vulnerability has been discovered in the zlib routines which are also present in the Linux kernel and allows remote attackers to crash the kernel. - CVE-2005-2548 Peter Sandstrom noticed that snmpwalk from a remote host could cause a denial of service (kernel oops from null dereference) via certain UDP packets that lead to a function call with the wrong argument. - CVE-2005-2801 Andreas Gruenbacher discovered a bug in the ext2 and ext3 file systems. When data areas are to be shared among two inodes not all information were compared for equality, which could expose wrong ACLs for files. - CVE-2005-2872 Chad Walstrom discovered that the ipt_recent kernel module on 64-bit processors such as AMD64 allows remote attackers to cause a denial of service (kernel panic) via certain attacks such as SSH brute force. - CVE-2005-3105 The mprotect code on Itanium IA-64 Montecito processors does not properly maintain cache coherency as required by the architecture, which allows local users to cause a denial of service and possibly corrupt data by modifying PTE protections. - CVE-2005-3106 A race condition in the thread management may allow local users to cause a denial of service (deadlock) when threads are sharing memory and waiting for a thread that has just performed an exec. - CVE-2005-3107 When one thread is tracing another thread that shares the same memory map a local user could cause a denial of service (deadlock) by forcing a core dump when the traced thread is in the TASK_TRACED state. - CVE-2005-3108 A bug in the ioremap() system call has been discovered on the amd64 architecture that could allow local users to cause a denial of service or an information leak when performing a lookup of a non-existent memory page. - CVE-2005-3109 The HFS and HFS+ (hfsplus) modules allow local attackers to cause a denial of service (oops) by using hfsplus to mount a filesystem that is not hfsplus. - CVE-2005-3110 A race condition in the ebtables netfilter module on an SMP system running under high load may allow remote attackers to cause a denial of service (crash). - CVE-2005-3271 Roland McGrath discovered that exec() does not properly clear posix-timers in multi-threaded environments, which results in a resource leak and could allow a large number of multiple local users to cause a denial of service by using more posix-timers than specified by the quota for a single user. - CVE-2005-3272 The kernel allows remote attackers to poison the bridge forwarding table using frames that have already been dropped by filtering, which can cause the bridge to forward spoofed packets. - CVE-2005-3273 The ioctl for the packet radio ROSE protocol does not properly verify the arguments when setting a new router, which allows attackers to trigger out-of-bounds errors. - CVE-2005-3274 A race condition on SMP systems allows local users to cause a denial of service (null dereference) by causing a connection timer to expire while the connection table is being flushed before the appropriate lock is acquired. - CVE-2005-3275 An error in the NAT code allows remote attackers to cause a denial of service (memory corruption) by causing two packets for the same protocol to be NATed at the same time, which leads to memory corruption. - CVE-2005-3276 A missing memory cleanup in the thread handling routines before copying data into userspace allows a user process to obtain sensitive information. This update also contains a number of corrections for issues that turned out to have no security implication afterwards.

    descriptionOleg Nesterov discovered a local Denial of Service vulnerability in the timer handling. When a non group-leader thread called exec() to execute a different program while an itimer was pending, the timer expiry would signal the old group leader task, which did not exist any more. This caused a kernel panic. This vulnerability only affects Ubuntu 5.04. (CAN-2005-1913) Al Viro discovered that the sendmsg() function did not sufficiently validate its input data. By calling sendmsg() and at the same time modifying the passed message in another thread, he could exploit this to execute arbitrary commands with kernel privileges. This only affects the amd64 bit platform. (CAN-2005-2490) Al Viro discovered a vulnerability in the raw_sendmsg() function. By calling this function with specially crafted arguments, a local attacker could either read kernel memory contents (leading to information disclosure) or manipulate the hardware state by reading certain IO ports. This vulnerability only affects Ubuntu 5.04. (CAN-2005-2492) Jan Blunck discovered a Denial of Service vulnerability in the procfs interface of the SCSI driver. By repeatedly reading /proc/scsi/sg/devices, a local attacker could eventually exhaust kernel memory. (CAN-2005-2800) A flaw was discovered in the handling of extended attributes on ext2 and ext3 file systems. Under certain condidions, this could prevent the enforcement of Access Control Lists, which eventually could lead to information disclosure, unauthorized program execution, or unauthorized data modification. This does not affect the standard Unix permissions. (CAN-2005-2801) Chad Walstrom discovered a Denial of Service in the ipt_recent module, which can be used in netfilter (Firewall configuration). A remote attacker could exploit this to crash the kernel by sending certain packets (such as an SSH brute-force attack) to a host which uses the
