Trustix Secure Linux Security Advisory #2005-0049

Package names: kernel, util-linux, xorg-x11
Summary: Multiple vulnerabilities
Date: 2005-09-16
Affected versions: Trustix Secure Linux 2.2
Trustix Secure Linux 3.0
Trustix Operating System - Enterprise Server 2

- --------------------------------------------------------------------------
Package description:
The kernel package contains the Linux kernel (vmlinuz), the core of your
Trustix Secure Linux operating system. The kernel handles the basic
functions of the operating system: memory allocation, process allocation,
device input and output, etc.

The util-linux package contains a large variety of low-level system
utilities that are necessary for a Linux system to function. Among
many features, Util-linux contains the fdisk configuration tool and
the login program.

xorg-x11 X11 is an open source implementation of the X Window System. It
provides the basic low level functionality which full fledged graphical
user interfaces (GUIs) such as GNOME and KDE are designed upon.

Problem description:
kernel < TSL 3.0 >
- SECURITY Fix: Fix unchecked __get_user that could be tricked into
generating a memory read on an arbitrary address. The result of the
read is not returned directly but you may be able to divine some
information about it, or use the read to cause a crash on some
architectures by reading hardware state.

The Common Vulnerabilities and Exposures project has assigned the
name CAN-2005-2492 to this issue.

- SECURITY Fix: Al Viro reported a flaw in sendmsg(). "When we copy
32bit ->msg_control contents to kernel, we walk the same userland data
twice without sanity checks on the second pass. Moreover, if original
looks small enough, we end up copying to on-stack array."

The Common Vulnerabilities and Exposures project has assigned the
name CAN-2005-2490 to this issue.

util-linux < TSL 3.0 > < TSL 2.2 > < TSEL-2 >
- SECURITY Fix: unintentional grant of privileges by umount in util-linux
allows local users with unmount permissions to gain privileges via the
-r (remount) option, which causes the file system to be remounted with
just the read-only flag, which effectively clears the nosuid, nodev,
and other flags. (SA16795)

xorg-x11 < TSL 3.0 >
- SECURITY Fix: Heap overflow in pixmap allocation, An integer overflow
in pixmap memory allocation potentially allows any xorg-x11 user to
execute arbitrary code with elevated privileges.

The Common Vulnerabilities and Exposures project has assigned the
name CAN-2005-2495 to this issue.

We recommend that all systems with this package installed be upgraded.
Please note that if you do not need the functionality provided by this
package, you may want to remove it from your system.
