"A number of vulnerabilities are fixed in the 2.4 and 2.6 kernels with
this advisory :

  - Multiple race conditions in the terminal layer of 2.4
    and 2.6 kernels (prior to 2.6.9) can allow a local
    attacker to obtain portions of kernel data or allow
    remote attackers to cause a kernel panic by switching
    from console to PPP line discipline, then quickly
    sending data that is received during the switch
    (CVE-2004-0814)

  - Richard Hart found an integer underflow problem in the
    iptables firewall logging rules that can allow a remote
    attacker to crash the machine by using a specially
    crafted IP packet. This is only possible, however, if
    firewalling is enabled. The problem only affects 2.6
    kernels and was fixed upstream in 2.6.8 (CVE-2004-0816)

  - Stefan Esser found several remote DoS confitions in the
    smbfs file system. This could be exploited by a hostile
    SMB server (or an attacker injecting packets into the
    network) to crash the client systems (CVE-2004-0883 and
    CVE-2004-0949)

  - Paul Starzetz and Georgi Guninski reported,
    independently, that bad argument handling and bad
    integer arithmetics in the IPv4 sendmsg handling of
    control messages could lead to a local attacker crashing
    the machine. The fixes were done by Herbert Xu
    (CVE-2004-1016)

  - Rob Landley discovered a race condition in the handling
    of /proc/.../cmdline where, under rare circumstances, a
    user could read the environment variables of another
    process that was still spawning leading to the potential
    disclosure of sensitive information such as passwords
    (CVE-2004-1058)

  - Paul Starzetz reported that the missing serialization in
    unix_dgram_recvmsg() which was added to kernel 2.4.28
    can be used by a local attacker to gain elevated (root)
    privileges (CVE-2004-1068)

  - Ross Kendall Axe discovered a possible kernel panic
    (DoS) while sending AF_UNIX network packets if certain
    SELinux-related kernel options were enabled. By default
    the CONFIG_SECURITY_NETWORK and CONFIG_SECURITY_SELINUX
    options are not enabled (CVE-2004-1069)

  - Paul Starzetz of isec.pl discovered several issues with
    the error handling of the ELF loader routines in the
    kernel. The fixes were provided by Chris Wright
    (CVE-2004-1070, CVE-2004-1071, CVE-2004-1072,
    CVE-2004-1073)

  - It was discovered that hand-crafted a.out binaries could
    be used to trigger a local DoS condition in both the 2.4
    and 2.6 kernels. The fixes were done by Chris Wright
    (CVE-2004-1074)

  - Paul Starzetz found bad handling in the IGMP code which
    could lead to a local attacker being able to crash the
    machine. The fix was done by Chris Wright
    (CVE-2004-1137)

  - Jeremy Fitzhardinge discovered two buffer overflows in
    the sys32_ni_syscall() and sys32_vm86_warning()
    functions that could be used to overwrite kernel memory
    with attacker-supplied code resulting in privilege
    escalation (CVE-2004-1151)

  - Paul Starzetz found locally exploitable flaws in the
    binary format loader's uselib() function that could be
    abused to allow a local user to obtain root privileges
    (CVE-2004-1235)

  - Paul Starzetz found an exploitable flaw in the page
    fault handler when running on SMP machines
    (CVE-2005-0001)

  - A vulnerability in insert_vm_struct could allow a locla
    user to trigger BUG() when the user created a large vma
    that overlapped with arg pages during exec
    (CVE-2005-0003)

  - Paul Starzetz also found a number of vulnerabilities in
    the kernel binfmt_elf loader that could lead a local
    user to obtain elevated (root) privileges
    (isec-0017-binfmt_elf)

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels.

To update your kernel, please follow the directions located at :

http://www.mandrakesoft.com/security/kernelupdate

PLEASE NOTE: Mandrakelinux 10.0 users will need to upgrade to the
latest module-init-tools package prior to upgrading their kernel.
Likewise, MNF8.2 users will need to upgrade to the latest modutils
package prior to upgrading their kernel."
