INFORMATION BULLETIN
INFORMATION BULLETIN
| PROBLEM: | Vulnerabilities in 32bit emulation code, IGMP functionality, scm_send function, ia64 architecture context switch code, and load_elf_binary code were discovered. |
| PLATFORM: | Linux Kernel 2.4.x Red Hat Desktop (v.3) & (v. 4) Red Hat Enterprise Linux AS, ES, WS (v. 2.1 and 3) & (v. 4) Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor Debian GNU/Linux 3.0 alias woody |
| DAMAGE: | A local attacker could use the 32bit emulation code vulnerability to gain privileges. Multiple vulnerabilities in IGMP functionality which were backported in Red Hat Enterprise Linux 3 kernels may allow a local attacker to cause a denial of service or gain privileges. A flaw in the scm_send function in the auxiliary message layer may allow an attacker to craft an auxiliary message which could cause a denial of service. A floating point information leak was discovered in the ia64 architecture context switch code which may allow an attacker to read register values of other processes by setting the MFH bit. A flaw in the load-elf-binary affecting kernels prior to 2.4.26 may allow a local attacker to craft a binary in such a way to cause a crash. |
| SOLUTION: | Apply the updated packages. |
| VULNERABILITY ASSESSMENT: |
The risk is LOW. The worst of these vulnerabilities may allow a local attacker to gain elevated privileges. |

Security Advisory
Details:
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 CAN-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 CAN-2004-1137 to
this issue.
ISEC security research and Georgi Guninski independantly 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 CAN-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 CAN-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 CAN-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.
Updated packages:
