RHEL 2.1 : kernel (RHSA-2006:0191)

This script is Copyright (C) 2006-2016 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated kernel packages that fix a number of security issues as well
as other bugs are now available for Red Hat Enterprise Linux 2.1 (32
bit architectures)

This security advisory has been rated as having important security
impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the security issues
described below :

- a flaw in network IGMP processing that a allowed a
remote user on the local network to cause a denial of
service (disabling of multicast reports) if the system
is running multicast applications (CVE-2002-2185,

- a race condition that allowed local users to read the
environment variables of another process (CVE-2004-1058,

- a flaw in the open_exec function of execve that allowed
a local user to read setuid ELF binaries that should
otherwise be protected by standard permissions.
(CVE-2004-1073, moderate). Red Hat originally reported
this flaw as being fixed by RHSA-2004:504, but a patch
for this issue was missing from that update.

- a flaw in the coda module that allowed a local user to
cause a denial of service (crash) or possibly gain
privileges (CVE-2005-0124, moderate)

- a potential leak of kernel data from ext2 file system
handling (CVE-2005-0400, low)

- flaws in ISO-9660 file system handling that allowed the
mounting of an invalid image on a CD-ROM to cause a
denial of service (crash) or potentially execute
arbitrary code (CVE-2005-0815, moderate)

- a flaw in gzip/zlib handling internal to the kernel that
may allow a local user to cause a denial of service
(crash) (CVE-2005-2458, low)

- a flaw in procfs handling during unloading of modules
that allowed a local user to cause a denial of service
or potentially gain privileges (CVE-2005-2709, moderate)

- a flaw in IPv6 network UDP port hash table lookups that
allowed a local user to cause a denial of service (hang)
(CVE-2005-2973, important)

- a network buffer info leak using the orinoco driver that
allowed a remote user to possibly view uninitialized
data (CVE-2005-3180, important)

- a flaw in IPv4 network TCP and UDP netfilter handling
that allowed a local user to cause a denial of service
(crash) (CVE-2005-3275, important)

- a flaw in the IPv6 flowlabel code that allowed a local
user to cause a denial of service (crash)
(CVE-2005-3806, important)

The following bugs were also addressed :

- Handle set_brk() errors in binfmt_elf/aout

- Correct error handling in shmem_ioctl

- Correct scsi error return

- Fix netdump time keeping bug

- Fix netdump link-down freeze

- Fix FAT fs deadlock

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum.
