Vulnerability from csaf_redhat - Published: 2005-08-25 13:29 - Updated: 2024-11-21 23:56
Summary
Red Hat Security Advisory: kernel security update
Severity
Important
Notes
Topic: Updated kernel packages that fix a number of security issues as well as other bugs are now available for Red Hat Enterprise Linux 2.1 (32 bit architectures) This update has been rated as having important security impact by the Red Hat Security Response Team.
Details: The Linux kernel handles the basic functions of the operating system. This is a kernel maintenance update to Red Hat Enterprise Linux 2.1. The following security issues were corrected: A flaw between execve() syscall handling and core dumping of ELF-format executables allowed local unprivileged users to cause a denial of service (system crash) or possibly gain privileges. The Common Vulnerabilities and Exposures project has assigned the name CAN-2005-1263 to this issue. A flaw when freeing a pointer in load_elf_library was discovered. A local user could potentially use this flaw to cause a denial of service (crash). (CAN-2005-0749) The Direct Rendering Manager (DRM) driver did not properly check the DMA lock, which could allow remote attackers or local users to cause a denial of service (X Server crash) or possibly modify the video output. (CAN-2004-1056) A flaw in the moxa serial driver could allow a local user to perform privileged operations such as replacing the firmware. (CAN-2005-0504) The following bug fixes were also made: - Fix a race condition that can cause a panic in __get_lease() - Fix a race condition that can cause a panic when reading /proc/mdstat - Fix incorrect ide accounting - Prevent non-root users from reloading moxa driver firmware - Fix a null-pointer-dereference bug in rpciod - Fix legacy-usb handoff for certain IBM platforms - Fix a bug that caused busy inodes after unmount - Provide an additional fix for a memory leak in scsi_scan_single. - Fix a potential kswapd/dquot deadlock. - Fix a potential local DoS in shmemfs. - Fix a random poolsize vulnerability. Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to the packages associated with their machine configurations as listed in this erratum.

CVE-2004-1056

Direct Rendering Manager (DRM) driver in Linux kernel 2.6 does not properly check the DMA lock, which could allow remote attackers or local users to cause a denial of service (X Server crash) and possibly modify the video output.

Vendor Fix Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. https://access.redhat.com/errata/RHSA-2005:529
CVE-2005-0504

Buffer overflow in the MoxaDriverIoctl function for the moxa serial driver (moxa.c) in Linux 2.2.x, 2.4.x, and 2.6.x before 2.6.22 allows local users to execute arbitrary code via a certain modified length value.

Vendor Fix Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. https://access.redhat.com/errata/RHSA-2005:529
CVE-2005-0749

The load_elf_library in the Linux kernel before 2.6.11.6 allows local users to cause a denial of service (kernel crash) via a crafted ELF library or executable, which causes a free of an invalid pointer.

Vendor Fix Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. https://access.redhat.com/errata/RHSA-2005:529
CVE-2005-1263

The elf_core_dump function in binfmt_elf.c for Linux kernel 2.x.x to 2.2.27-rc2, 2.4.x to 2.4.31-pre1, and 2.6.x to 2.6.12-rc4 allows local users to execute arbitrary code via an ELF binary that, in certain conditions involving the create_elf_tables function, causes a negative length argument to pass a signed integer comparison, leading to a buffer overflow.

Vendor Fix Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. https://access.redhat.com/errata/RHSA-2005:529
