The remote host is missing the patch for the advisory SuSE-SA:2004:005 (Linux Kernel).


Another bug in the Kernel's do_mremap() function, which is unrelated to the bug fixed in SuSE-SA:2004:001, was found by Paul Starzetz.
The do_mremap() function of the Linux Kernel is used to manage Virtual Memory Areas (VMAs) which includes moving, removing and resizing of memory areas.  To remove old memory areas do_mremap() uses the function du_munmap() without checking the return value.
By forcing do_munmap() to return an error the memory management of a process can be tricked into moving page table entries from one VMA to another. The destination VMA may be protected by a different ACL which enables a local attacker to gain write access to previous read-only pages.
The result will be local root access to the system.

Additionally to the bug mentioned above some other bugs were fixed (depending on architecture) that can cause local denial-of-service conditions:
- Vicam USB driver: CVE-2004-0075 + denial-of-service due to problem while copying data from user to kernel space
- Direct Render Infrastructure: CVE-2004-0003 + denial-of-service due to integer overflow + needs r128 card and console to be exploited
- ncpfs/ncp_lookup: CVE-2004-0010 + buffer overflow with the probability to gain root
- execve():
+ malformed elf binaries can lead to a local denial-of-service attack

Paul Staretz discovered a flaw in return value checking in the mremap() function in the Linux kernel, versions 2.4.24 and previous that could allow a local user to obtain root privileges.

A vulnerability was found in the R128 DRI driver by Alan Cox. This could allow local privilege escalation.

A flaw in the ncp_lookup() function in the ncpfs code (which is used to mount NetWare volumes or print to NetWare printers) was found by Arjen van de Ven that could allow local privilege escalation.

The Vicam USB driver in Linux kernel versions prior to 2.4.25 does not use the copy_from_user function to access userspace, which crosses security boundaries. This problem does not affect the Mandrake Linux 9.2 kernel.

Additionally, a ptrace hole that only affects the amd64/x86_64 platform has been corrected.

The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels.

Updated kernel packages are now available that fix a few security issues, an NFS performance issue, and an e1000 driver loading issue introduced in Update 3.

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

Alan Cox found issues in the R128 Direct Render Infrastructure that could allow local privilege escalation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0003 to this issue.

The C-Media PCI sound driver in Linux before 2.4.22 does not use the get_user function to access userspace in certain conditions, which crosses security boundaries. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0700 to this issue.

An overflow was found in the ixj telephony card driver in Linux kernels prior to 2.4.20. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2002-1574 to this issue.

All users are advised to upgrade to these errata packages, which contain backported security patches that corrects these issues. These packages also contain a fix to enhance NFS performance, which was degraded in the last kernel update as part of Update 3.

Updated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 3. This is the second regular update.

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

This is the second regular kernel update to Red Hat Enterprise Linux version 3. It contains several minor security fixes, many bug fixes, device driver updates, new hardware support, and the introduction of Linux Syscall Auditing support.

There were bug fixes in many different parts of the kernel, the bulk of which addressed unusual situations such as error handling, race conditions, and resource starvation. The combined effect of the approximately 140 fixes is a strong improvement in the reliability and durability of Red Hat Enterprise Linux. Some of the key areas affected are disk drivers, network drivers, USB support, x86_64 and ppc64 platform support, ia64 32-bit emulation layer enablers, and the VM, NFS, IPv6, and SCSI subsystems.

A significant change in the SCSI subsystem (the disabling of the scsi-affine-queue patch) should significantly improve SCSI disk driver performance in many scenarios. There were 10 Bugzillas against SCSI performance problems addressed by this change.

The following drivers have been upgraded to new versions :

bonding ---- 2.4.1 cciss ------ 2.4.50.RH1 e1000 ------ 5.2.30.1-k1 fusion ----- 2.05.11.03 ipr -------- 1.0.3 ips -------- 6.11.07 megaraid2 -- 2.10.1.1 qla2x00 ---- 6.07.02-RH1 tg3 -------- 3.1 z90crypt --- 1.1.4

This update introduces support for the new Intel EM64T processor. A new 'ia32e' architecture has been created to support booting on platforms based on either the original AMD Opteron CPU or the new Intel EM64T CPU. The existing 'x86_64' architecture has remained optimized for Opteron systems. Kernels for both types of systems are built from the same x86_64-architecture sources and share a common kernel source RPM (kernel-source-2.4.21-15.EL.x86_64.rpm).

Other highlights in this update include a major upgrade to the SATA infrastructure, addition of IBM JS20 Power Blade support, and creation of an optional IBM eServer zSeries On-Demand Timer facility for reducing idle CPU overhead.

The following security issues were addressed in this update :

A minor flaw was found where /proc/tty/driver/serial reveals the exact character counts for serial links. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0461 to this issue.

The kernel strncpy() function in Linux 2.4 and 2.5 does not pad the target buffer with null bytes on architectures other than x86, as opposed to the expected libc behavior, which could lead to information leaks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0465 to this issue.

A minor data leak was found in two real time clock drivers (for /dev/rtc). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0984 to this issue.

A flaw in the R128 Direct Render Infrastructure (dri) driver could allow local privilege escalation. This driver is part of the kernel-unsupported package. The Common Vulnera- bilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0003 to this issue.

A flaw in ncp_lookup() in ncpfs could allow local privilege escalation. The ncpfs module allows a system to mount volumes of NetWare servers or print to NetWare printers and is in the kernel-unsupported package. The Common Vulnera- bilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0010 to this issue.

(Note that the kernel-unsupported package contains drivers and other 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.

A vulnerability was found in the R128 DRI driver by Alan Cox. This could allow local privilege escalation. The previous fix, in MDKSA-2004:015 only partially corrected the problem; the full fix is included (CVE-2004-0003).

A local root vulnerability was discovered in the isofs component of the Linux kernel by iDefense. This vulnerability can be triggered by performing a directory listing on a maliciously constructed ISO filesystem, or attempting to access a file via a malformed symlink on such a filesystem (CVE-2004-0109).

An information leak was discovered in the ext3 filesystem code by Solar Designer. It was discovered that when creating or writing to an ext3 filesystem, some amount of other in-memory data gets written to the device. The data is not the file's contents, not something on the same filesystem, or even anything that was previously in a file at all. To obtain this data, a user needs to read the raw device (CVE-2004-0177).

The same vulnerability was also found in the XFS filesystem code (CVE-2004-0133) and the JFS filesystem code (CVE-2004-0181).

Finally, a vulnerability in the OSS code for SoundBlaster 16 devices was discovered by Andreas Kies. It is possible for local users with access to the sound system to crash the machine (CVE-2004-0178).

The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels.
