------------------------------------------------------------
---------------------------------------------------------------------
Red Hat Security Advisory
Synopsis: Updated glibc packages fix vulnerabilities in RPC XDR decoder
Advisory ID: RHSA-2003:089-00
Issue date: 2003-04-10
Updated on: 2003-04-10
Product: Red Hat Linux
Keywords: sun RPC XDR integer overflow
Cross references:
Obsoletes: RHSA-2002:166
CVE Names: CAN-2003-0028
---------------------------------------------------------------------
1. Topic:
Updated glibc packages are available to fix an integer overflow in
the XDR decoder.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - i386
Red Hat Linux 7.0 - i386, i686
Red Hat Linux 7.1 - i386, i686
Red Hat Linux 7.2 - i386, i686, ia64
Red Hat Linux 7.3 - i386, i686
Red Hat Linux 8.0 - i386, i686
3. Problem description:
The glibc package contains standard libraries that are used by
multiple programs on the system. Sun RPC is a remote procedure call
framework that allows clients to invoke procedures in a server
process over a network. XDR is a mechanism for encoding data
structures for use with RPC. Glibc contains an XDR encoder/decoder
derived from Sun's RPC implementation, which was demonstrated to be
vulnerable to an integer overflow.
An integer overflow is present in the xdrmem_getbytes() function of
glibc 2.3.1 and earlier. Depending upon the application, this
vulnerability could cause buffer overflows and may be exploitable
leading to arbitrary code execution.
All users should upgrade to these errata packages which contain
patches to the glibc libraries and therefore are not vulnerable to
these issues.
Red Hat would like to thank eEye Digital Security for alerting us to
this issue.
The Red Hat Linux 8.0 errata packages also contain a number of bug
fixes that are not security related. For details, see the list of
bugzilla bugs fixed by this errata or the ChangeLog.
[Updated 9 April 2003]
Some bugs newly introduced by the Red Hat Linux 8.0 errata packages
has been discovered, such as wine problems or problems with debugging
threaded applications.
Once the glibc upgrade has been completed, you must either reboot the
system or restart all programs on the system (for example, by using
telinit 1 and switching back to the old runlevel). Rebooting the
system or restarting the system programs is necessary to avoid
vulnerable glibc copies in memory and because changes in NSS internal
interfaces which mean that one cannot mix old NSS modules or
libresolv in an application with upgraded NSS modules or libresolv in
one running application.
If sshd is running so that the other services can be restarted
remotely or for a remote reboot during an unattended glibc upgrade,
glibc will also restart sshd.
4. 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.
