Mandriva Advisories

Package name	kernel
Date	January 25th, 2005
Advisory ID	MDKSA-2005:022
Affected versions	9.2, 10.0, 10.1, MNF8.2, CS2.1, CS3.0
Synopsis	Updated kernel packages fix multiple vulnerabilities

Problem Description

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 (CAN-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 (CAN-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 (CAN-2004-0883 and CAN-2004-0949)

- Paul Starzetz and Georgi Guninski reported, independantly, 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 (CAN-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 (CAN-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 (CAN-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 (CAN-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 (CAN-2004-1070, CAN-2004-1071,
CAN-2004-1072, CAN-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 (CAN-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 (CAN-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 (CAN-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 (CAN-2004-1235)

- Paul Starzetz found an exploitable flaw in the page fault handler
when running on SMP machines (CAN-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 (CAN-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.

Upgrade

To upgrade your kernel, view the kernel update instructions. Kernels cannot be upgraded via MandrivaUpdate.

Verification

Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command :

                rpm --checksig package.rpm

You can get the GPG public key of the Mandriva Security Team to verify the GPG signature of each RPM.
