NOTE: This kernel update marks the final planned kernel security update for the 2.6.24 kernel in the Debian release 'etch'. Although security support for 'etch' officially ended on Feburary 15th, 2010, this update was already in preparation before that date.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-2691     Steve Beattie and Kees Cook reported an information leak     in the maps and smaps files available under /proc. Local     users may be able to read this data for setuid processes     while the ELF binary is being loaded.

  - CVE-2009-2695     Eric Paris provided several fixes to increase the     protection provided by the mmap_min_addr tunable against     NULL pointer dereference vulnerabilities.

  - CVE-2009-3080     Dave Jones reported an issue in the gdth SCSI driver. A     missing check for negative offsets in an ioctl call     could be exploited by local users to create a denial of     service or potentially gain elevated privileges.

  - CVE-2009-3726     Trond Myklebust reported an issue where a malicious NFS     server could cause a denial of service condition on its     clients by returning incorrect attributes during an open     call.

  - CVE-2009-3889     Joe Malicki discovered an issue in the megaraid_sas     driver. Insufficient permissions on the sysfs dbg_lvl     interface allow local users to modify the debug logging     behavior.

  - CVE-2009-4005     Roel Kluin discovered an issue in the hfc_usb driver, an     ISDN driver for Colognechip HFC-S USB chip. A potential     read overflow exists which may allow remote users to     cause a denial of service condition (oops).

  - CVE-2009-4020     Amerigo Wang discovered an issue in the HFS filesystem     that would allow a denial of service by a local user who     has sufficient privileges to mount a specially crafted     filesystem.

  - CVE-2009-4021     Anana V. Avati discovered an issue in the fuse     subsystem. If the system is sufficiently low on memory,     a local user can cause the kernel to dereference an     invalid pointer resulting in a denial of service (oops)     and potentially an escalation of privileges.

  - CVE-2009-4138     Jay Fenlason discovered an issue in the firewire stack     that allows local users to cause a denial of service     (oops or crash) by making a specially crafted ioctl     call.

  - CVE-2009-4308     Ted Ts'o discovered an issue in the ext4 filesystem that     allows local users to cause a denial of service (NULL     pointer dereference). For this to be exploitable, the     local user must have sufficient privileges to mount a     filesystem.

  - CVE-2009-4536 CVE-2009-4538     Fabian Yamaguchi reported issues in the e1000 and e1000e     drivers for Intel gigabit network adapters which allow     remote users to bypass packet filters using specially     crafted Ethernet frames.

  - CVE-2010-0003     Andi Kleen reported a defect which allows local users to     gain read access to memory reachable by the kernel when     the print-fatal-signals option is enabled. This option     is disabled by default.

  - CVE-2010-0007     Florian Westphal reported a lack of capability checking     in the ebtables netfilter subsystem. If the ebtables     module is loaded, local users can add and modify     ebtables rules.

  - CVE-2010-0291     Al Viro reported several issues with the mmap/mremap     system calls that allow local users to cause a denial of     service (system panic) or obtain elevated privileges.

  - CVE-2010-0410     Sebastian Krahmer discovered an issue in the netlink     connector subsystem that permits local users to allocate     large amounts of system memory resulting in a denial of     service (out of memory).

  - CVE-2010-0415     Ramon de Carvalho Valle discovered an issue in the     sys_move_pages interface, limited to amd64, ia64 and     powerpc64 flavors in Debian. Local users can exploit     this issue to cause a denial of service (system crash)     or gain access to sensitive kernel memory.

  - CVE-2010-0622     Jerome Marchand reported an issue in the futex subsystem     that allows a local user to force an invalid futex state     which results in a denial of service (oops).

   Notes :
   - The update also addresses the 64-bit compatibility mode    stack pointer underflow issue identified by CVE-2010-3081. This    issue was patched in an ESX 4.1 patch prior to the release of    ESX 4.1 Update 1 and in a previous ESX 4.0 patch release.
   - The update also addresses CVE-2010-2240 for ESX 4.0.

This update fixes the following security issues :

  - multiple flaws were found in the mmap and mremap     implementations. A local user could use these flaws to     cause a local denial of service or escalate their     privileges. (CVE-2010-0291, Important)

  - a NULL pointer dereference flaw was found in the Fast     Userspace Mutexes (futexes) implementation. The unlock     code path did not check if the futex value associated     with pi_state->owner had been modified. A local user     could use this flaw to modify the futex value, possibly     leading to a denial of service or privilege escalation     when the pi_state->owner pointer is dereferenced.
    (CVE-2010-0622, Important)

  - a NULL pointer dereference flaw was found in the Linux     kernel Network File System (NFS) implementation. A local     user on a system that has an NFS-mounted file system     could use this flaw to cause a denial of service or     escalate their privileges on that system.
    (CVE-2010-1087, Important)

  - a flaw was found in the sctp_process_unk_param()     function in the Linux kernel Stream Control Transmission     Protocol (SCTP) implementation. A remote attacker could     send a specially crafted SCTP packet to an SCTP     listening port on a target system, causing a kernel     panic (denial of service). (CVE-2010-1173, Important)

  - a flaw was found in the Linux kernel Transparent     Inter-Process Communication protocol (TIPC)     implementation. If a client application, on a local     system where the tipc module is not yet in network mode,     attempted to send a message to a remote TIPC node, it     would dereference a NULL pointer on the local system,     causing a kernel panic (denial of service).
    (CVE-2010-1187, Important)

  - a buffer overflow flaw was found in the Linux kernel     Global File System 2 (GFS2) implementation. In certain     cases, a quota could be written past the end of a memory     page, causing memory corruption, leaving the quota     stored on disk in an invalid state. A user with write     access to a GFS2 file system could trigger this flaw to     cause a kernel crash (denial of service) or escalate     their privileges on the GFS2 server. This issue can only     be triggered if the GFS2 file system is mounted with the     'quota=on' or 'quota=account' mount option.
    (CVE-2010-1436, Important)

  - a race condition between finding a keyring by name and     destroying a freed keyring was found in the Linux kernel     key management facility. A local user could use this     flaw to cause a kernel panic (denial of service) or     escalate their privileges. (CVE-2010-1437, Important)

  - a flaw was found in the link_path_walk() function in the     Linux kernel. Using the file descriptor returned by the     open() function with the O_NOFOLLOW flag on a     subordinate NFS-mounted file system, could result in a     NULL pointer dereference, causing a denial of service or     privilege escalation. (CVE-2010-1088, Moderate)

  - a missing permission check was found in the     gfs2_set_flags() function in the Linux kernel GFS2     implementation. A local user could use this flaw to     change certain file attributes of files, on a GFS2 file     system, that they do not own. (CVE-2010-1641, Low)

_Update/ index.html

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.

Amerigo Wang and Eric Sesterhenn discovered that the HFS and ext4 filesystems did not correctly check certain disk structures. If a user were tricked into mounting a specially crafted filesystem, a remote attacker could crash the system or gain root privileges.
(CVE-2009-4020, CVE-2009-4308)

It was discovered that FUSE did not correctly check certain requests.
A local attacker with access to FUSE mounts could exploit this to crash the system or possibly gain root privileges. Ubuntu 9.10 was not affected. (CVE-2009-4021)

It was discovered that KVM did not correctly decode certain guest instructions. A local attacker in a guest could exploit this to trigger high scheduling latency in the host, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-4031)

It was discovered that the OHCI fireware driver did not correctly handle certain ioctls. A local attacker could exploit this to crash the system, or possibly gain root privileges. Ubuntu 6.06 was not affected. (CVE-2009-4138)

Tavis Ormandy discovered that the kernel did not correctly handle O_ASYNC on locked files. A local attacker could exploit this to gain root privileges. Only Ubuntu 9.04 and 9.10 were affected.
(CVE-2009-4141)

Neil Horman and Eugene Teo discovered that the e1000 and e1000e network drivers did not correctly check the size of Ethernet frames.
An attacker on the local network could send specially crafted traffic to bypass packet filters, crash the system, or possibly gain root privileges. (CVE-2009-4536, CVE-2009-4538)

It was discovered that 'print-fatal-signals' reporting could show arbitrary kernel memory contents. A local attacker could exploit this, leading to a loss of privacy. By default this is disabled in Ubuntu and did not affect Ubuntu 6.06. (CVE-2010-0003)

Olli Jarva and Tuomo Untinen discovered that IPv6 did not correctly handle jumbo frames. A remote attacker could exploit this to crash the system, leading to a denial of service. Only Ubuntu 9.04 and 9.10 were affected. (CVE-2010-0006)

Florian Westphal discovered that bridging netfilter rules could be modified by unprivileged users. A local attacker could disrupt network traffic, leading to a denial of service. (CVE-2010-0007)

Al Viro discovered that certain mremap operations could leak kernel memory. A local attacker could exploit this to consume all available memory, leading to a denial of service. (CVE-2010-0291).

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.

The remote CentOS system is missing a security update which has been documented in Red Hat advisory RHSA-2010-0504.
