SuSE Security Update: Kernel Update for SUSE Linux 10.1 (kernel-4193)

This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote SuSE system is missing the security patch kernel-4193.

Description :

This kernel update brings the kernel to the one shipped
with SLES 10 Service Pack 1 and also fixes the following
security problems:

- CVE-2007-2242: The IPv6 protocol allows remote attackers
to cause a denial of service via crafted IPv6 type 0
route headers (IPV6_RTHDR_TYPE_0) that create network
amplification between two routers.

The default is that RH0 is disabled now. To adjust this,
write to the file /proc/net/accept_source_route6.

- CVE-2007-2453: The random number feature in the Linux
kernel 2.6 (1) did not properly seed pools when there is
no entropy, or (2) used an incorrect cast when extracting
entropy, which might have caused the random number
generator to provide the same values after reboots on
systems without an entropy source.

- CVE-2007-2876: A NULL pointer dereference in SCTP
connection tracking could be caused by a remote attacker
by sending specially crafted packets. Note that this
requires SCTP set-up and active to be exploitable.

- CVE-2007-3105: Stack-based buffer overflow in the random
number generator (RNG) implementation in the Linux kernel
before 2.6.22 might allow local root users to cause a
denial of service or gain privileges by setting the
default wakeup threshold to a value greater than the
output pool size, which triggers writing random numbers
to the stack by the pool transfer function involving
'bound check ordering'.

Since this value can only be changed by a root user,
exploitability is low.

- CVE-2007-3107: The signal handling in the Linux kernel,
when run on PowerPC systems using HTX, allows local users
to cause a denial of service via unspecified vectors
involving floating point corruption and concurrency.

- CVE-2007-2525: Memory leak in the PPP over Ethernet
(PPPoE) socket implementation in the Linux kernel allowed
local users to cause a denial of service (memory
consumption) by creating a socket using connect, and
releasing it before the PPPIOCGCHAN ioctl is initialized.

- CVE-2007-3513: The lcd_write function in
drivers/usb/misc/usblcd.c in the Linux kernel did not
limit the amount of memory used by a caller, which
allowed local users to cause a denial of service (memory
consumption).

- CVE-2007-3851: On machines with a Intel i965 based
graphics card local users with access to the direct
rendering devicenode could overwrite memory on the
machine and so gain root privileges.

This kernel is not compatible to the previous SUSE Linux
10.1 kernel, so the Kernel Module Packages will need to be
updated.

Solution :

Install the security patch kernel-4193.
