local user to cause a denial of service or potentially gain privileges
(CVE-2005-2709)
- a flaw in the SCSI procfs interface that allowed a local user to cause
a denial of service (crash) (CVE-2005-2800)
- a xattr sharing bug in the ext2 and ext3 file systems that could cause
default ACLs to disappear (CVE-2005-2801)
- a flaw in the ipt_recent module on 64-bit architectures which could
allow a remote denial of service (CVE-2005-2872)
- 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)
- a flaw in 32-bit-compat handling of the TIOCGDEV ioctl that allowed
a local user to cause a denial of service (crash) (CVE-2005-3044)
- a flaw in the set_mempolicy system call that allowed a local user to
cause a denial of service (system panic). (CVE-2005-3053)
- a race condition when threads share memory mapping that allowed local
users to cause a denial of service (deadlock) (CVE-2005-3106)

All users are advised to upgrade their kernels to the packages
associated with their machine architectures and configurations as listed
in this erratum.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To install kernel packages manually, use "rpm -ivh <package>" and modify
system settings to boot the kernel you have installed. To do this, edit
/boot/grub/grub.conf and change the default entry to "default=0" (or, if
you have chosen to use LILO as your boot loader, edit /etc/lilo.conf and
run lilo)
Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:
yum update
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
Note that this may not automatically pull the new kernel in if you have
configured apt/yum to ignore kernels. If so, follow the manual
instructions above.
