"Updated kernel packages that fix several security issues in Red Hat
Enterprise Linux 2.1 are now available.

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

This advisory includes fixes for the following security issues :

iSEC Security Research discovered a VMA handling flaw in the uselib(2)
system call of the Linux kernel. A local user could make use of this
flaw to gain elevated (root) privileges. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1235 to this issue.

iSEC Security Research discovered a flaw in the page fault handler
code that could lead to local users gaining elevated (root) privileges
on multiprocessor machines. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2005-0001 to this
issue.

iSEC Security Research and Georgi Guninski independently discovered a
flaw in the scm_send function in the auxiliary message layer. A local
user could create a carefully crafted auxiliary message which could
cause a denial of service (system hang). The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1016 to this issue.

Kirill Korotaev found a flaw in load_elf_binary affecting kernels
prior to 2.4.26. A local user could create a carefully crafted binary
in such a way that it would cause a denial of service (system crash).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-1234 to this issue.

These packages also fix issues in the io_edgeport driver
(CVE-2004-1017), a memory leak in ip_options_get (CVE-2004-1335), and
missing VM_IO flags in some drivers (CVE-2004-1057).

A recent Internet Draft by Fernando Gont recommended that ICMP Source
Quench messages be ignored by hosts. A patch to ignore these messages
is included.

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."
