| Descripción: | Description:
The remote host is missing updates announced in
advisory RHSA-2006:0190.
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, moderate)
- - a race condition that allowed local users to read the environment
variables of another process (CVE-2004-1058, low)
- - 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 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 exec() handling on some 64-bit architectures that allowed a
local user to cause a denial of service (crash) (CVE-2005-2708, important)
- - 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 race condition affecting SMP systems that allowed a local user to cause
a denial of service (crash) (CVE-2005-3274, 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
- - Correct scsi error return
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.
Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
