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.

Updated kernel packages that fix several security issues in Red Hat Enterprise Linux 3 are now available.

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

This advisory includes fixes for several security issues :

Petr Vandrovec discovered a flaw in the 32bit emulation code affecting the Linux 2.4 kernel on the AMD64 architecture. A local attacker could use this flaw to gain privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1144 to this issue.

ISEC security research discovered multiple vulnerabilities in the IGMP functionality which was backported in the Red Hat Enterprise Linux 3 kernels. These flaws could allow a local user to cause a denial of service (crash) or potentially gain privileges. Where multicast applications are being used on a system, these flaws may also allow remote users to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1137 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.

A floating point information leak was discovered in the ia64 architecture context switch code. A local user could use this flaw to read register values of other processes by setting the MFH bit. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0565 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, and a memory leak in ip_options_get.

Note: The kernel-unsupported package contains various drivers and modules that are unsupported and therefore might contain security problems that have not been addressed.

All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.
