ID CVE-2009-3286
Summary NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.

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 a. vMA and Service Console update for newt to 0.52.2-12.el5_4.1 Newt is a programming library for color text mode, widget based user interfaces. Newt can be used to add stacked windows, entry widgets, checkboxes, radio buttons, labels, plain text fields, scrollbars, etc., to text mode user interfaces. A heap-based buffer overflow flaw was found in the way newt processes content that is to be displayed in a text dialog box. A local attacker could issue a specially crafted text dialog box display request (direct or via a custom application), leading to a denial of service (application crash) or, potentially, arbitrary code execution with the privileges of the user running the application using the newt library. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2905 to this issue. b. vMA and Service Console update for vMA package nfs-utils to 1.0.9-42.el5 The nfs-utils package provides a daemon for the kernel NFS server and related tools. It was discovered that nfs-utils did not use tcp_wrappers correctly. Certain hosts access rules defined in '/etc/hosts.allow' and '/etc/hosts.deny' may not have been honored, possibly allowing remote attackers to bypass intended access restrictions. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2008-4552 to this issue. c. vMA and Service Console package glib2 updated to 2.12.3-4.el5_3.1 GLib is the low-level core library that forms the basis for projects such as GTK+ and GNOME. It provides data structure handling for C, portability wrappers, and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system. Multiple integer overflows in glib/gbase64.c in GLib before 2.20 allow context-dependent attackers to execute arbitrary code via a long string that is converted either from or to a base64 representation. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2008-4316 to this issue. d. vMA and Service Console update for openssl to 0.9.8e-12.el5 SSL is a toolkit implementing SSL v2/v3 and TLS protocols with full- strength cryptography world-wide. Multiple denial of service flaws were discovered in OpenSSL's DTLS implementation. A remote attacker could use these flaws to cause a DTLS server to use excessive amounts of memory, or crash on an invalid memory access or NULL pointer dereference. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-1377, CVE-2009-1378, CVE-2009-1379, CVE-2009-1386, CVE-2009-1387 to these issues. An input validation flaw was found in the handling of the BMPString and UniversalString ASN1 string types in OpenSSL's ASN1_STRING_print_ex() function. An attacker could use this flaw to create a specially crafted X.509 certificate that could cause applications using the affected function to crash when printing certificate contents. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-0590 to this issue. e. vMA and Service Console package bind updated to 9.3.6-4.P1.el5_4.1 It was discovered that BIND was incorrectly caching responses without performing proper DNSSEC validation, when those responses were received during the resolution of a recursive client query that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4022 to this issue. f. vMA and Service Console package expat updated to 1.95.8-8.3.el5_4.2. Two buffer over-read flaws were found in the way Expat handled malformed UTF-8 sequences when processing XML files. A specially- crafted XML file could cause applications using Expat to fail while parsing the file. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-3560 and CVE-2009-3720 to these issues. g. vMA and Service Console package openssh update to 4.3p2-36.el5_4.2 A Red Hat specific patch used in the openssh packages as shipped in Red Hat Enterprise Linux 5.4 (RHSA-2009:1287) loosened certain ownership requirements for directories used as arguments for the ChrootDirectory configuration options. A malicious user that also has or previously had non-chroot shell access to a system could possibly use this flaw to escalate their privileges and run commands as any system user. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2904 to this issue. h. vMA and Service Console package ntp updated to ntp-4.2.2p1-9.el5_4.1.i386.rpm A flaw was discovered in the way ntpd handled certain malformed NTP packets. ntpd logged information about all such packets and replied with an NTP packet that was treated as malformed when received by another ntpd. A remote attacker could use this flaw to create an NTP packet reply loop between two ntpd servers through a malformed packet with a spoofed source IP address and port, causing ntpd on those servers to use excessive amounts of CPU time and fill disk space with log messages. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-3563 to this issue. i. vMA update for package kernel to 2.6.18-164.9.1.el5 Updated vMA package kernel addresses the security issues listed below. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-2849 to the security issue fixed in kernel 2.6.18-128.2.1 The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-2695, CVE-2009-2908, CVE-2009-3228, CVE-2009-3286, CVE-2009-3547, CVE-2009-3613 to the security issues fixed in kernel 2.6.18-128.6.1 The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-3612, CVE-2009-3620, CVE-2009-3621, CVE-2009-3726 to the security issues fixed in kernel 2.6.18-128.9.1 j. vMA 4.0 updates for the packages kpartx, libvolume-id, device-mapper-multipath, fipscheck, dbus, dbus-libs, and ed kpartx updated to 0.4.7-23.el5_3.4, libvolume-id updated to 095-14.20.el5 device-mapper-multipath package updated to 0.4.7-23.el5_3.4, fipscheck updated to 1.0.3-1.el5, dbus updated to 1.1.2-12.el5, dbus-libs updated to 1.1.2-12.el5, and ed package updated to 0.2-39.el5_2.

ESXi userworld update for ntp The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source. A vulnerability in ntpd could allow a remote attacker to cause a denial of service (CPU and bandwidth consumption) by using MODE_PRIVATE to send a spoofed (1) request or (2) response packet that triggers a continuous exchange of MODE_PRIVATE error responses between two NTP daemons. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-3563 to this issue. c. Service Console package openssl updated to 0.9.8e-12.el5_4.1 OpenSSL is a toolkit implementing SSL v2/v3 and TLS protocols with full-strength cryptography world-wide. A memory leak in the zlib could allow a remote attacker to cause a denial of service (memory consumption) via vectors that trigger incorrect calls to the CRYPTO_cleanup_all_ex_data function. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4355 to this issue. A vulnerability was discovered which may allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2409 to this issue. This update also includes security fixes that were first addressed in version openssl-0.9.8e-12.el5.i386.rpm. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-0590, CVE-2009-1377, CVE-2009-1378, CVE-2009-1379, CVE-2009-1386 and CVE-2009-1387 to these issues. d. Service Console update for krb5 to 1.6.1-36.el5_4.1 and pam_krb5 to 2.2.14-15. Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. Multiple integer underflows in the AES and RC4 functionality in the crypto library could allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by providing ciphertext with a length that is too short to be valid. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4212 to this issue. The service console package for pam_krb5 is updated to version pam_krb5-2.2.14-15. This update fixes a flaw found in pam_krb5. In some non-default configurations (specifically, where pam_krb5 would be the first module to prompt for a password), a remote attacker could use this flaw to recognize valid usernames, which would aid a dictionary-based password guess attack. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-1384 to this issue. e. Service Console package bind updated to 9.3.6-4.P1.el5_4.2 BIND (Berkeley Internet Name Daemon) is by far the most widely used Domain Name System (DNS) software on the Internet. A vulnerability was discovered which could allow remote attacker to add the Authenticated Data (AD) flag to a forged NXDOMAIN response for an existing domain. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0097 to this issue. A vulnerability was discovered which could allow remote attackers to conduct DNS cache poisoning attacks by receiving a recursive client query and sending a response that contains CNAME or DNAME records, which do not have the intended validation before caching. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0290 to this issue. A vulnerability was found in the way that bind handles out-of- bailiwick data accompanying a secure response without re-fetching from the original source, which could allow remote attackers to have an unspecified impact via a crafted response. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0382 to this issue. NOTE: ESX does not use the BIND name service daemon by default. f. Service Console package gcc updated to 3.2.3-60 The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages GNU Libtool's ltdl.c attempts to open .la library files in the current working directory. This could allow a local user to gain privileges via a Trojan horse file. The GNU C Compiler collection (gcc) provided in ESX contains a statically linked version of the vulnerable code, and is being replaced. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-3736 to this issue. g. Service Console package gzip update to 1.3.3-15.rhel3 gzip is a software application used for file compression An integer underflow in gzip's unlzw function on 64-bit platforms may allow a remote attacker to trigger an array index error leading to a denial of service (application crash) or possibly execute arbitrary code via a crafted LZW compressed file. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0001 to this issue. h. Service Console package sudo updated to 1.6.9p17-6.el5_4 Sudo (su 'do') allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments. When a pseudo-command is enabled, sudo permits a match between the name of the pseudo-command and the name of an executable file in an arbitrary directory, which allows local users to gain privileges via a crafted executable file. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0426 to this issue. When the runas_default option is used, sudo does not properly set group memberships, which allows local users to gain privileges via a sudo command. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0427 to this issue.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_11_0_KERNEL-100203.NASL
    description This kernel update for openSUSE 11.0 fixes some bugs and several security problems. The following security issues are fixed: CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload. CVE-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets. CVE-2010-0007: Missing CAP_NET_ADMIN checks in the ebtables netfilter code might have allowed local attackers to modify bridge firewall settings. CVE-2010-0003: An information leakage on fatal signals on x86_64 machines was fixed. CVE-2009-4138: drivers/firewire/ohci.c in the Linux kernel, when packet-per-buffer mode is used, allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unknown other impact via an unspecified ioctl associated with receiving an ISO packet that contains zero in the payload-length field. CVE-2009-4308: The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference), and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal. CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file. CVE-2009-4021: The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel before 2.6.32-rc7 might allow attackers to cause a denial of service (invalid pointer dereference and OOPS) via vectors possibly related to a memory-consumption attack. CVE-2009-3547: A race condition in the pipe(2) systemcall could be used by local attackers to hang the machine. The kernel in Moblin 2.0 uses NULL ptr protection which avoids code execution possbilities. CVE-2009-2903: Memory leak in the appletalk subsystem in the Linux kernel 2.4.x through 2.4.37.6 and 2.6.x through 2.6.31, when the appletalk and ipddp modules are loaded but the ipddp'N' device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams. CVE-2009-3621: net/unix/af_unix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket. CVE-2009-3612: The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. CVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. CVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state. CVE-2009-3286: NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails. CVE-2009-2910: arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x86_64 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode. CVE-2009-3238: The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to 'return the same value over and over again for long stretches of time.' CVE-2009-2848: The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit. CVE-2009-3002: The Linux kernel before 2.6.31-rc7 does not initialize certain data structures within getname functions, which allows local users to read the contents of some kernel memory locations by calling getsockname on (1) an AF_APPLETALK socket, related to the atalk_getname function in net/appletalk/ddp.c; (2) an AF_IRDA socket, related to the irda_getname function in net/irda/af_irda.c; (3) an AF_ECONET socket, related to the econet_getname function in net/econet/af_econet.c; (4) an AF_NETROM socket, related to the nr_getname function in net/netrom/af_netrom.c; (5) an AF_ROSE socket, related to the rose_getname function in net/rose/af_rose.c; or (6) a raw CAN socket, related to the raw_getname function in net/can/raw.c. CVE-2009-1633: Multiple buffer overflows in the cifs subsystem in the Linux kernel before 2.6.29.4 allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or (2) long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c.

  • NASL family Oracle Linux Local Security Checks
    NASL id ORACLELINUX_ELSA-2009-1548.NASL
    description From Red Hat Security Advisory 2009:1548 : Updated kernel packages that fix multiple security issues and several 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. Security fixes : * a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important) * a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel. A local attacker could use this flaw to cause a local denial of service or escalate their privileges. (CVE-2009-2908, Important) * a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission check after creating a file. This check would usually fail and leave the file with the permission bits set to random values. Note: This is a server-side only issue. (CVE-2009-3286, 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's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) * a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could abuse this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important) * missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks. (CVE-2009-3228, Moderate) Bug fixes : * with network bonding in the 'balance-tlb' or 'balance-alb' mode, the primary setting for the primary slave device was lost when said device was brought down. Bringing the slave back up did not restore the primary setting. (BZ#517971) * some faulty serial device hardware caused systems running the kernel-xen kernel to take a very long time to boot. (BZ#524153) * a caching bug in nfs_readdir() may have caused NFS clients to see duplicate files or not see all files in a directory. (BZ#526960) * the RHSA-2009:1243 update removed the mpt_msi_enable option, preventing certain scripts from running. This update adds the option back. (BZ#526963) * an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#527434) * 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. (BZ#527436) * a kernel panic occurred in certain conditions after reconfiguring a tape drive's block size. (BZ#528133) * when using the Linux Virtual Server (LVS) in a master and backup configuration, and propagating active connections on the master to the backup, the connection timeout value on the backup was hard-coded to 180 seconds, meaning connection information on the backup was soon lost. This could prevent the successful failover of connections. The timeout value can now be set via 'ipvsadm --set'. (BZ#528645) * a bug in nfs4_do_open_expired() could have caused the reclaimer thread on an NFSv4 client to enter an infinite loop. (BZ#529162) * MSI interrupts may not have been delivered for r8169 based network cards that have MSI interrupts enabled. This bug only affected certain systems. (BZ#529366) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    NASL id SUSE_11_KERNEL-091123.NASL
    description The SUSE Linux Enterprise 11 Kernel was updated to 2.6.27.39 fixing various bugs and security issues. The following security issues have been fixed : - A race condition during pipe open could be used by local attackers to cause a denial of service. (Due to mmap_min_addr protection enabled by default, code execution is not possible.). (CVE-2009-3547) - On x86_64 systems a information leak of high register contents (upper 32bit) was fixed. (CVE-2009-2910) - Memory leak in the appletalk subsystem in the Linux kernel when the appletalk and ipddp modules are loaded but the ipddp'N' device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams. (CVE-2009-2903) - net/1/af_unix.c in the Linux kernel allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket. (CVE-2009-3621) - The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. NOTE: this issue existed because of an incomplete fix for CVE-2005-4881. (CVE-2009-3612 / CVE-2005-4881) - The ATI Rage 128 (aka r128) driver in the Linux kernel does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. (CVE-2009-3620) - The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state. (CVE-2009-3726) - Sv4 in the Linux kernel does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.

    description CVE-2009-2695 kernel: SELinux and mmap_min_addr CVE-2009-3228 kernel: tc: uninitialised kernel memory leak CVE-2009-3286 kernel: O_EXCL creates on NFSv4 are broken CVE-2009-2908 kernel ecryptfs NULL pointer dereference CVE-2009-3613 kernel: flood ping cause out-of-iommu error and panic when mtu larger than 1500 CVE-2009-3547 kernel: fs: pipe.c NULL pointer dereference Security fixes : - a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important) - a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel. A local attacker could use this flaw to cause a local denial of service or escalate their privileges. (CVE-2009-2908, Important) - a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission check after creating a file. This check would usually fail and leave the file with the permission bits set to random values. Note: This is a server-side only issue. (CVE-2009-3286, 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's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) - a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could abuse this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important) - missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks. (CVE-2009-3228, Moderate) Bug fixes : - with network bonding in the 'balance-tlb' or 'balance-alb' mode, the primary setting for the primary slave device was lost when said device was brought down. Bringing the slave back up did not restore the primary setting. (BZ#517971) - some faulty serial device hardware caused systems running the kernel-xen kernel to take a very long time to boot. (BZ#524153) - a caching bug in nfs_readdir() may have caused NFS clients to see duplicate files or not see all files in a directory. (BZ#526960) - the RHSA-2009:1243 update removed the mpt_msi_enable option, preventing certain scripts from running. This update adds the option back. (BZ#526963) - an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#527434) - 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. (BZ#527436) - a kernel panic occurred in certain conditions after reconfiguring a tape drive's block size. (BZ#528133) - when using the Linux Virtual Server (LVS) in a master and backup configuration, and propagating active connections on the master to the backup, the connection timeout value on the backup was hard-coded to 180 seconds, meaning connection information on the backup was soon lost. This could prevent the successful failover of connections. The timeout value can now be set via 'ipvsadm --set'. (BZ#528645) - a bug in nfs4_do_open_expired() could have caused the reclaimer thread on an NFSv4 client to enter an infinite loop. (BZ#529162) - MSI interrupts may not have been delivered for r8169 based network cards that have MSI interrupts enabled. This bug only affected certain systems. (BZ#529366) The system must be rebooted for this update to take effect. Note1: Due to the fuse kernel module now being part of the kernel, we are updating fuse on the older releases to match the fuse that was released by The Upstream Vendor. Note2: kernel-module-openafs for SL 50-53 is for openafs 1.4.7, for SL 54 it is for openafs 1.4.11 Note3: xfs is now part of the kernel in x86_64. Because of this there is no kernel-module-xfs for x86_64. Note4: ipw3945 support has been changed to iwlwifi3945 in SL 54, and is in the kernel. Because of this there is no kernel-module-ipw3945 for SL54. Note5: Support for the Atheros chipset in now in the kernel. We are not sure if the infrastructure is in place for SL 50-53, so we are still providing the madwifi kernel modules for SL 50-53.

    description Solar Designer discovered that the z90crypt driver did not correctly check capabilities. A local attacker could exploit this to shut down the device, leading to a denial of service. Only affected Ubuntu 6.06. (CVE-2009-1883) Michael Buesch discovered that the SGI GRU driver did not correctly check the length when setting options. A local attacker could exploit this to write to the kernel stack, leading to root privilege escalation or a denial of service. Only affected Ubuntu 8.10 and 9.04. (CVE-2009-2584) It was discovered that SELinux did not fully implement the mmap_min_addr restrictions. A local attacker could exploit this to allocate the NULL memory page which could lead to further attacks against kernel NULL-dereference vulnerabilities. Ubuntu 6.06 was not affected. (CVE-2009-2695) Cagri Coltekin discovered that the UDP stack did not correctly handle certain flags. A local user could send specially crafted commands and traffic to gain root privileges or crash the systeam, leading to a denial of service. Only affected Ubuntu 6.06. (CVE-2009-2698) Hiroshi Shimamoto discovered that monotonic timers did not correctly validate parameters. A local user could make a specially crafted timer request to gain root privileges or crash the system, leading to a denial of service. Only affected Ubuntu 9.04. (CVE-2009-2767) Michael Buesch discovered that the HPPA ISA EEPROM driver did not correctly validate positions. A local user could make a specially crafted request to gain root privileges or crash the system, leading to a denial of service. (CVE-2009-2846) Ulrich Drepper discovered that kernel signal stacks were not being correctly padded on 64-bit systems. A local attacker could send specially crafted calls to expose 4 bytes of kernel stack memory, leading to a loss of privacy. (CVE-2009-2847) Jens Rosenboom discovered that the clone method did not correctly clear certain fields. A local attacker could exploit this to gain privileges or crash the system, leading to a denial of service. (CVE-2009-2848) It was discovered that the MD driver did not check certain sysfs files. A local attacker with write access to /sys could exploit this to cause a system crash, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-2849) Mark Smith discovered that the AppleTalk stack did not correctly manage memory. A remote attacker could send specially crafted traffic to cause the system to consume all available memory, leading to a denial of service. (CVE-2009-2903) Loic Minier discovered that eCryptfs did not correctly handle writing to certain deleted files. A local attacker could exploit this to gain root privileges or crash the system, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-2908) It was discovered that the LLC, AppleTalk, IR, EConet, Netrom, and ROSE network stacks did not correctly initialize their data structures. A local attacker could make specially crafted calls to read kernel memory, leading to a loss of privacy. (CVE-2009-3001, CVE-2009-3002) It was discovered that the randomization used for Address Space Layout Randomization was predictable within a small window of time. A local attacker could exploit this to leverage further attacks that require knowledge of userspace memory layouts. (CVE-2009-3238) Eric Paris discovered that NFSv4 did not correctly handle file creation failures. An attacker with write access to an NFSv4 share could exploit this to create files with arbitrary mode bits, leading to privilege escalation or a loss of privacy. (CVE-2009-3286) Bob Tracy discovered that the SCSI generic driver did not correctly use the right index for array access. A local attacker with write access to a CDR could exploit this to crash the system, leading to a denial of service. Only Ubuntu 9.04 was affected. (CVE-2009-3288) Jan Kiszka discovered that KVM did not correctly validate certain hypercalls. A local unprivileged attacker in a virtual guest could exploit this to crash the guest kernel, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-3290). 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.

    NASL id SUSE_11_1_KERNEL-091123.NASL
    description The openSUSE 11.1 Kernel was updated to 2.6.27.39 fixing various bugs and security issues. Following security issues have been fixed: CVE-2009-3547: A race condition during pipe open could be used by local attackers to cause a denial of service. (Due to mmap_min_addr protection enabled by default, code execution is not possible.) CVE-2009-2910: On x86_64 systems a information leak of high register contents (upper 32bit) was fixed. CVE-2009-2903: Memory leak in the appletalk subsystem in the Linux kernel when the appletalk and ipddp modules are loaded but the ipddp'N' device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams. CVE-2009-3621: net/unix/af_unix.c in the Linux kernel allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket. CVE-2009-3612 / CVE-2005-4881: The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. NOTE: this issue existed because of an incomplete fix for CVE-2005-4881. CVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. CVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state. CVE-2009-3286: Sv4 in the Linux kernel does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.
