CWE CWE-119
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.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • 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.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description Updated kernel packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.0 Extended Update Support. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue : * A flaw allowed napi_reuse_skb() to be called on VLAN (virtual LAN) packets. An attacker on the local network could trigger this flaw by sending specially crafted packets to a target system, possibly causing a denial of service. (CVE-2011-1576, Moderate) Red Hat would like to thank Ryan Sweat for reporting this issue. This update also fixes the following bugs : * The LSI SAS2 controller firmware issued an 0x620f fault while performing I/O operations and with a Task Manager running, causing possible data corruption. This update corrects this issue. (BZ#710625) * The crashkernel memory region can overlap the RunTime Abstraction Services (RTAS) memory region. If the crashkernel memory region was freed, the RTAS memory region was freed as well and the system would crash. With this update, the crash_free_reserved_phys_range() function is overridden and overlaps with the RTAS memory region are checked so that system crashes no longer occur. (BZ#710626) * If the microcode module was loaded, saving and restoring a Xen guest returned a warning message and a backtrace error. With this update, backtrace errors are no longer returned, and saving and restoring a Xen guest works as expected. (BZ#710632) * When the Distributed Lock Manager (DLM) queued three callbacks for a lock in the following sequence: blocking - completion - blocking, it would consider the final blocking callback redundant and skip it. Because the callback was skipped, GFS would not release the lock, causing processes on other nodes to wait indefinitely for it. With this update, the DLM does not skip the necessary blocking callback. (BZ#710642) * The XFRM_SUB_POLICY feature causes all bundles to be at the finest granularity possible. As a result of the data structure used to implement this, the system performance would drop considerably. This update disables a part of XFRM_SUB_POLICY, eliminating the poor performance at the cost of sub-IP address selection granularity in the policy. (BZ#710645) * A kernel panic in the mpt2sas driver could occur on an IBM system using a drive with SMART (Self-Monitoring, Analysis and Reporting Technology) issues. This was because the driver was sending an SEP request while the kernel was in the interrupt context, causing the driver to enter the sleep state. With this update, a fake event is now executed from the interrupt context, assuring the SEP request is properly issued. (BZ#714189) Finally, this update provides the following enhancements : * This update introduces a kernel module option that allows the Flow Director to be disabled. (BZ#711549) * This update introduces parallel port printer support for Red Hat Enterprise Linux 6. (BZ#713825) * This update restricts access to the /proc/kcore file to ELF headers only. (BZ#710638) Users should upgrade to these updated packages, which contain backported patches to resolve these issues and add these enhancements. The system must be rebooted for this update to take effect.

    description Description of changes: * CVE-2011-4127: KVM privilege escalation through insufficient validation in SG_IO ioctl. Using the SG_IO IOCTL to issue SCSI requests to partitions or LVM volumes resulted in the requests being passed to the underlying block device. If a privileged user only had access to a single partition or LVM volume, they could use this flaw to bypass those restrictions and gain read and write access (and be able to issue other SCSI commands) to the entire block device. In KVM (Kernel-based Virtual Machine) environments using raw format virtio disks backed by a partition or LVM volume, a privileged guest user could bypass intended restrictions and issue read and write requests (and other SCSI commands) on the host, and possibly access the data of other guests that reside on the same underlying block device. (CVE-2011-4127, Important) * CVE-2011-1493: Insufficient validation in X.25 Rose parsing. Dan Rosenberg discovered that the X.25 Rose network stack did not correctly handle certain fields. If a system was running with Rose enabled, a remote attacker could send specially crafted traffic to gain root privileges. * Additional fix for CVE-2011-1576: Denial of service with VLAN packets and GRO.

    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-2011-1020 Kees Cook discovered an issue in the /proc filesystem that allows local users to gain access to sensitive process information after execution of a setuid binary. - CVE-2011-1576 Ryan Sweat discovered an issue in the VLAN implementation. Local users may be able to cause a kernel memory leak, resulting in a denial of service. - CVE-2011-2484 Vasiliy Kulikov of Openwall discovered that the number of exit handlers that a process can register is not capped, resulting in local denial of service through resource exhaustion (CPU time and memory). - CVE-2011-2491 Vasily Averin discovered an issue with the NFS locking implementation. A malicious NFS server can cause a client to hang indefinitely in an unlock call. - CVE-2011-2492 Marek Kroemeke and Filip Palian discovered that uninitialized struct elements in the Bluetooth subsystem could lead to a leak of sensitive kernel memory through leaked stack memory. - CVE-2011-2495 Vasiliy Kulikov of Openwall discovered that the io file of a process' proc directory was world-readable, resulting in local information disclosure of information such as password lengths. - CVE-2011-2496 Robert Swiecki discovered that mremap() could be abused for local denial of service by triggering a BUG_ON assert. - CVE-2011-2497 Dan Rosenberg discovered an integer underflow in the Bluetooth subsystem, which could lead to denial of service or privilege escalation. - CVE-2011-2517 It was discovered that the netlink-based wireless configuration interface performed insufficient length validation when parsing SSIDs, resulting in buffer overflows. Local users with the CAP_NET_ADMIN capability can cause a denial of service. - CVE-2011-2525 Ben Pfaff reported an issue in the network scheduling code. A local user could cause a denial of service (NULL pointer dereference) by sending a specially crafted netlink message. - CVE-2011-2700 Mauro Carvalho Chehab of Red Hat reported a buffer overflow issue in the driver for the Si4713 FM Radio Transmitter driver used by N900 devices. Local users could exploit this issue to cause a denial of service or potentially gain elevated privileges. - CVE-2011-2723 Brent Meshier reported an issue in the GRO (generic receive offload) implementation. This can be exploited by remote users to create a denial of service (system crash) in certain network device configurations. - CVE-2011-2905 Christian Ohm discovered that the 'perf' analysis tool searches for its config files in the current working directory. This could lead to denial of service or potential privilege escalation if a user with elevated privileges is tricked into running 'perf' in a directory under the control of the attacker. - CVE-2011-2909 Vasiliy Kulikov of Openwall discovered that a programming error in the Comedi driver could lead to the information disclosure through leaked stack memory. - CVE-2011-2918 Vince Weaver discovered that incorrect handling of software event overflows in the 'perf' analysis tool could lead to local denial of service. - CVE-2011-2928 Timo Warns discovered that insufficient validation of Be filesystem images could lead to local denial of service if a malformed filesystem image is mounted. - CVE-2011-3188 Dan Kaminsky reported a weakness of the sequence number generation in the TCP protocol implementation. This can be used by remote attackers to inject packets into an active session. - CVE-2011-3191 Darren Lavender reported an issue in the Common Internet File System (CIFS).

    description The SUSE Linux Enterprise 11 Service Pack 1 kernel has been updated to version 2.6.32.49 and fixes various bugs and security issues. - The TCP/IP initial sequence number generation effectively only used 24 bits of 32 to generate randomness, making a brute-force man-in-the-middle attack on TCP/IP connections feasible. The generator was changed to use full 32bit randomness. (CVE-2011-3188) - Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service. (CVE-2011-2699) - A NULL ptr dereference on mounting corrupt hfs filesystems was fixed which could be used by local attackers to crash the kernel. (CVE-2011-2203) - Added a kernel option to ensure ecryptfs is mounting only on paths belonging to the current ui, which would have allowed local attackers to potentially gain privileges via symlink attacks. (CVE-2011-1833) - The Generic Receive Offload (GRO) implementation in the Linux kernel allowed remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478. (CVE-2011-1576) - A name overflow in the hfs filesystem was fixed, where mounting a corrupted hfs filesystem could lead to a stack overflow and code execution in the kernel. This requires a local attacker to be able to mount hfs filesystems. (CVE-2011-4330) - A bug was found in the way headroom check was performed in udp6_ufo_fragment() function. A remote attacker could use this flaw to crash the system. (CVE-2011-4326) The following non-security bugs have been fixed : - ALSA: hda - Fix S3/S4 problem on machines with VREF-pin mute-LED.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_11_3_KERNEL-120104.NASL
    description The openSUSE 11.3 kernel was updated to fix various bugs and security issues. Following security issues have been fixed: CVE-2011-4604: If root does read() on a specific socket, it's possible to corrupt (kernel) memory over network, with an ICMP packet, if the B.A.T.M.A.N. mesh protocol is used. CVE-2011-2525: A flaw allowed the tc_fill_qdisc() function in the Linux kernels packet scheduler API implementation to be called on built-in qdisc structures. A local, unprivileged user could have used this flaw to trigger a NULL pointer dereference, resulting in a denial of service. CVE-2011-2699: Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service. CVE-2011-2213: The inet_diag_bc_audit function in net/ipv4/inet_diag.c in the Linux kernel did not properly audit INET_DIAG bytecode, which allowed local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message, as demonstrated by an INET_DIAG_BC_JMP instruction with a zero yes value, a different vulnerability than CVE-2010-3880. CVE-2011-1576: The Generic Receive Offload (GRO) implementation in the Linux kernel allowed remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478. CVE-2011-2534: Buffer overflow in the clusterip_proc_write function in net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux kernel might have allowed local users to cause a denial of service or have unspecified other impact via a crafted write operation, related to string data that lacks a terminating '\0' character. CVE-2011-1770: Integer underflow in the dccp_parse_options function (net/dccp/options.c) in the Linux kernel allowed remote attackers to cause a denial of service via a Datagram Congestion Control Protocol (DCCP) packet with an invalid feature options length, which triggered a buffer over-read. CVE-2011-2723: The skb_gro_header_slow function in include/linux/netdevice.h in the Linux kernel, when Generic Receive Offload (GRO) is enabled, reset certain fields in incorrect situations, which allowed remote attackers to cause a denial of service (system crash) via crafted network traffic. CVE-2011-2898: A kernel information leak in the AF_PACKET protocol was fixed which might have allowed local attackers to read kernel memory. CVE-2011-2203: A NULL ptr dereference on mounting corrupt hfs filesystems was fixed which could be used by local attackers to crash the kernel. CVE-2011-4081: Using the crypto interface a local user could Oops the kernel by writing to a AF_ALG socket.

    NASL id SL_20110823_KERNEL_ON_SL6_X.NASL
    description Security issues : - Using PCI passthrough without interrupt remapping support allowed KVM guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. (CVE-2011-1898, Important) - Flaw in the client-side NLM implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2491, Important) - Integer underflow in the Bluetooth implementation could allow a remote attacker to cause a denial of service or escalate their privileges by sending a specially crafted request to a target system via Bluetooth. (CVE-2011-2497, Important) - Buffer overflows in the netlink-based wireless configuration interface implementation could allow a local user, who has the CAP_NET_ADMIN capability, to cause a denial of service or escalate their privileges on systems that have an active wireless interface. (CVE-2011-2517, Important) - Flaw in the way the maximum file offset was handled for ext4 file systems could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2695, Important) - Flaw allowed napi_reuse_skb() to be called on VLAN packets. An attacker on the local network could use this flaw to send crafted packets to a target, possibly causing a denial of service. (CVE-2011-1576, Moderate) - Integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate) - Race condition in the memory merging support (KSM) could allow a local, unprivileged user to cause a denial of service. KSM is off by default, but on systems running VDSM, or on KVM hosts, it is likely turned on by the ksm/ksmtuned services. (CVE-2011-2183, Moderate) - Flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2213, Moderate) - Flaw in the way space was allocated in the Global File System 2 (GFS2) implementation. If the file system was almost full, and a local, unprivileged user made an fallocate() request, it could result in a denial of service. Setting quotas to prevent users from using all available disk space would prevent exploitation of this flaw. (CVE-2011-2689, Moderate) - Local, unprivileged users could send signals via the sigqueueinfo system call, with si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. This flaw does not allow existing permission checks to be bypassed; signals can only be sent if your privileges allow you to already do so. (CVE-2011-1182, Low) - Heap overflow in the EFI GUID Partition Table (GPT) implementation could allow a local attacker to cause a denial of service by mounting a disk containing crafted partition tables. (CVE-2011-1776, Low) - Structure padding in two structures in the Bluetooth implementation was not initialized properly before being copied to user-space, possibly allowing local, unprivileged users to leak kernel stack memory to user-space. (CVE-2011-2492, Low) - /proc/[PID]/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to gather confidential information, such as the length of a password used in a process. (CVE-2011-2495, Low)

    NASL id ORACLELINUX_ELSA-2011-1189.NASL
    description From Red Hat Security Advisory 2011:1189 : Updated kernel packages that fix several security issues, various bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Security issues : * Using PCI passthrough without interrupt remapping support allowed KVM guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Refer to Red Hat Bugzilla bug 715555 for details. (CVE-2011-1898, Important) * Flaw in the client-side NLM implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2491, Important) * Integer underflow in the Bluetooth implementation could allow a remote attacker to cause a denial of service or escalate their privileges by sending a specially crafted request to a target system via Bluetooth. (CVE-2011-2497, Important) * Buffer overflows in the netlink-based wireless configuration interface implementation could allow a local user, who has the CAP_NET_ADMIN capability, to cause a denial of service or escalate their privileges on systems that have an active wireless interface. (CVE-2011-2517, Important) * Flaw in the way the maximum file offset was handled for ext4 file systems could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2695, Important) * Flaw allowed napi_reuse_skb() to be called on VLAN packets. An attacker on the local network could use this flaw to send crafted packets to a target, possibly causing a denial of service. (CVE-2011-1576, Moderate) * Integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate) * Race condition in the memory merging support (KSM) could allow a local, unprivileged user to cause a denial of service. KSM is off by default, but on systems running VDSM, or on KVM hosts, it is likely turned on by the ksm/ksmtuned services. (CVE-2011-2183, Moderate) * Flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2213, Moderate) * Flaw in the way space was allocated in the Global File System 2 (GFS2) implementation. If the file system was almost full, and a local, unprivileged user made an fallocate() request, it could result in a denial of service. Setting quotas to prevent users from using all available disk space would prevent exploitation of this flaw. (CVE-2011-2689, Moderate) * Local, unprivileged users could send signals via the sigqueueinfo system call, with si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. This flaw does not allow existing permission checks to be bypassed; signals can only be sent if your privileges allow you to already do so. (CVE-2011-1182, Low) * Heap overflow in the EFI GUID Partition Table (GPT) implementation could allow a local attacker to cause a denial of service by mounting a disk containing crafted partition tables. (CVE-2011-1776, Low) * Structure padding in two structures in the Bluetooth implementation was not initialized properly before being copied to user-space, possibly allowing local, unprivileged users to leak kernel stack memory to user-space. (CVE-2011-2492, Low) * /proc/[PID]/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to gather confidential information, such as the length of a password used in a process. (CVE-2011-2495, Low) Red Hat would like to thank Vasily Averin for reporting CVE-2011-2491; Dan Rosenberg for reporting CVE-2011-2497 and CVE-2011-2213; Ryan Sweat for reporting CVE-2011-1576; Robert Swiecki for reporting CVE-2011-1593; Andrea Righi for reporting CVE-2011-2183; Julien Tinnes of the Google Security Team for reporting CVE-2011-1182; Timo Warns for reporting CVE-2011-1776; Marek Kroemeke and Filip Palian for reporting CVE-2011-2492; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2495.

    description From Red Hat Security Advisory 2011:0927 : Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * An integer overflow flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2010-4649, Important) * A race condition in the way new InfiniBand connections were set up could allow a remote user to cause a denial of service. (CVE-2011-0695, Important) * A flaw in the Stream Control Transmission Protocol (SCTP) implementation could allow a remote attacker to cause a denial of service if the sysctl 'net.sctp.addip_enable' variable was turned on (it is off by default). (CVE-2011-1573, Important) * Flaws in the AGPGART driver implementation when handling certain IOCTL commands could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2011-1745, CVE-2011-2022, Important) * An integer overflow flaw in agp_allocate_memory() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2011-1746, Important) * A flaw allowed napi_reuse_skb() to be called on VLAN (virtual LAN) packets. An attacker on the local network could trigger this flaw by sending specially crafted packets to a target system, possibly causing a denial of service. (CVE-2011-1576, Moderate) * An integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate) * A flaw in the way the Xen hypervisor implementation handled CPUID instruction emulation during virtual machine exits could allow an unprivileged guest user to crash a guest. This only affects systems that have an Intel x86 processor with the Intel VT-x extension enabled. (CVE-2011-1936, Moderate) * A flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service (infinite loop). (CVE-2011-2213, Moderate) * A missing initialization flaw in the XFS file system implementation could lead to an information leak. (CVE-2011-0711, Low) * A flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause an information leak. (CVE-2011-1044, Low) * A missing validation check was found in the signals implementation. A local, unprivileged user could use this flaw to send signals via the sigqueueinfo system call, with the si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. Note: This flaw does not allow existing permission checks to be bypassed; signals can only be sent if your privileges allow you to already do so. (CVE-2011-1182, Low) * A heap overflow flaw in the EFI GUID Partition Table (GPT) implementation could allow a local attacker to cause a denial of service by mounting a disk containing specially crafted partition tables. (CVE-2011-1776, Low) * Structure padding in two structures in the Bluetooth implementation was not initialized properly before being copied to user-space, possibly allowing local, unprivileged users to leak kernel stack memory to user-space. (CVE-2011-2492, Low) Red Hat would like to thank Jens Kuehnel for reporting CVE-2011-0695; Vasiliy Kulikov for reporting CVE-2011-1745, CVE-2011-2022, and CVE-2011-1746; Ryan Sweat for reporting CVE-2011-1576; Robert Swiecki for reporting CVE-2011-1593; Dan Rosenberg for reporting CVE-2011-2213 and CVE-2011-0711; Julien Tinnes of the Google Security Team for reporting CVE-2011-1182; Timo Warns for reporting CVE-2011-1776; and Marek Kroemeke and Filip Palian for reporting CVE-2011-2492. Bug fix documentation will be available shortly from the Technical Notes document linked to in the References. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.
