RHSA-2004:106 - Security Advisory
Synopsis
kernel security update
Type/Severity
Security Advisory: Important
Topic
Updated IA64 kernel packages are now available that fix a security
vulnerability which may allow local users to gain root privileges and other
vulnerabilities.
Description
The Linux kernel handles the basic functions of the operating system.
This kernel updates several important drivers and fixes a number of bugs
including potential security vulnerabilities.
iDefense reported a buffer overflow flaw in the ISO9660 filesystem code.
An attacker could create a malicious filesystem in such a way that root
privileges may be obtained if the filesystem is mounted. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0109 to this issue.
A flaw in return value checking in mremap() in the Linux kernel versions
2.4.24 and previous that may allow a local attacker to gain root
privileges. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0077 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. This is part of the kernel-unsupported package.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0010 to this issue.
A flaw in the R128 Direct Render Infrastructure could allow local privilege
escalation. This driver is part of the kernel-unsupported package. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0003 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 CAN-2002-1574 to this issue.
The following drivers were updated:
IBM Serveraid 6.11.07
MPT fusion v. 2.05.11.03
Qlogic v. 6.07.02-RH1
All users are advised to upgrade to these errata packages, which contain
backported security patches that correct these issues.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. 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.
If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
