Test ID:1.3.6.1.4.1.25623.1.0.55135
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2005:529
Summary:NOSUMMARY
Description:Description:

The remote host is missing updates announced in
advisory RHSA-2005:529.

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 CVE-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).
(CVE-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.
(CVE-2004-1056)

A flaw in the moxa serial driver could allow a local user to perform
privileged operations such as replacing the firmware. (CVE-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.
