Scientific Linux Security Update : kernel on SL3.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

This update addresses the following security issues :

- Tavis Ormandy discovered a deficiency in the Linux
kernel 32-bit and 64-bit emulation. This could allow a
local, unprivileged user to prepare and run a
specially-crafted binary which would use this deficiency
to leak uninitialized and potentially sensitive data.
(CVE-2008-0598, Important)

- a possible kernel memory leak was found in the Linux
kernel Simple Internet Transition (SIT) INET6
implementation. This could allow a local, unprivileged
user to cause a denial of service. (CVE-2008-2136,
Important)

- missing capability checks were found in the SBNI WAN
driver which could allow a local user to bypass intended
capability restrictions. (CVE-2008-3525, Important)

- the do_truncate() and generic_file_splice_write()
functions did not clear the setuid and setgid bits. This
could allow a local, unprivileged user to obtain access
to privileged information. (CVE-2008-4210, Important)

- a buffer overflow flaw was found in Integrated Services
Digital Network (ISDN) subsystem. A local, unprivileged
user could use this flaw to cause a denial of service.
(CVE-2007-6063, Moderate)

- multiple NULL pointer dereferences were found in various
Linux kernel network drivers. These drivers were missing
checks for terminal validity, which could allow
privilege escalation. (CVE-2008-2812, Moderate)

- a deficiency was found in the Linux kernel virtual
filesystem (VFS) implementation. This could allow a
local, unprivileged user to attempt file creation within
deleted directories, possibly causing a denial of
service. (CVE-2008-3275, Moderate)

This update also fixes the following bugs :

- the incorrect kunmap function was used in
nfs_xdr_readlinkres. kunmap() was used where
kunmap_atomic() should have been. As a consequence, if
an NFSv2 or NFSv3 server exported a volume containing a
symlink which included a path equal to or longer than
the local system's PATH_MAX, accessing the link caused a
kernel oops. This has been corrected in this update.

- mptctl_gettargetinfo did not check if pIoc3 was NULL
before using it as a pointer. This caused a kernel panic
in mptctl_gettargetinfo in some circumstances. A check
has been added which prevents this.

- lost tick compensation code in the timer interrupt
routine triggered without apparent cause. When running
as a fully-virtualized client, this spurious triggering
caused the 64-bit version of Red Hat Enterprise Linux 3
to present highly inaccurate times. With this update the
lost tick compensation code is turned off when the
operating system is running as a fully-virtualized
client under Xen or VMware&reg
.
