Vulnerability Assessment Details

RHSA-2004-188: kernel

Vulnerability Assessment Summary
Check for the version of the kernel packages

Detailed Explanation for this Vulnerability Assessment


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.


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 permit 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 permit local privilege
escalation. The ncpfs module permits 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.
