Red Hat Linux Advisories: dhcp, vim

Jan 16, 2003, 15:52 (0 Talkback[s])

---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated dhcp packages fix security vulnerabilities
Advisory ID:       RHSA-2003:011-07
Issue date:        2003-01-16
Updated on:        2003-01-16
Product:           Red Hat Linux
Keywords:          
Cross references:  
Obsoletes:         
CVE Names:         CAN-2003-0026
---------------------------------------------------------------------

1. Topic:

Several potential stack overflow vulnerabilities affect the ISC DHCPD
server.  This advisory provides fixed packages for Red Hat Linux 8.0.

2. Relevant releases/architectures:

Red Hat Linux 8.0 - i386

3. Problem description:

The dhcp package provides the ISC Dynamic Host Configuration Protocol
(DHCP) server and relay agent.  DHCP is a protocol which allows devices to
get their own network configuration information from a server.

The Internet Software Consortium has detected several potential
vulnerabilities during an audit of the ISC DHCP server.  These
vulnerabilities affect the minires library and may be exploitable as stack
buffer overflows, which could lead to remote code execution.  

Red Hat Linux 8.0 shipped with a version of DHCP that is vulnerable to
these issues.  All users of DHCP are advised to upgrade to the erratum
packages which contain a backported patch to correct this issue.  Other
versions of Red Hat Linux and Red Hat Linux Advanced Server are based on
version 2 of DHCP, and are therefore not vulnerable to this issue.

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.

5. RPMs required:

Red Hat Linux 8.0:

SRPMS:
ftp://updates.redhat.com/8.0/en/os/SRPMS/dhcp-3.0pl1-15.src.rpm

i386:
ftp://updates.redhat.com/8.0/en/os/i386/dhcp-3.0pl1-15.i386.rpm
ftp://updates.redhat.com/8.0/en/os/i386/dhcp-devel-3.0pl1-15.i386.rpm
ftp://updates.redhat.com/8.0/en/os/i386/dhclient-3.0pl1-15.i386.rpm



6. Verification:

MD5 sum                          Package Name
--------------------------------------------------------------------------

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at http://www.redhat.com/about/contact/pgpkey.html

You can verify each package with the following command:
    
    rpm --checksig -v <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    
    md5sum <filename>

                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated vim packages fix modeline vulnerability
Advisory ID:       RHSA-2002:297-17
Issue date:        2003-01-16
Updated on:        2003-01-15
Product:           Red Hat Linux
Keywords:          vim modeline security
Cross references:  
Obsoletes:         RHEA-2002:017
CVE Names:         CAN-2002-1377
---------------------------------------------------------------------

1. Topic:

Updated vim packages are now available for Red Hat Linux.  These 
updates resolve a security issue when opening a specially crafted text 
file.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - i386
Red Hat Linux 7.0 - i386
Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386

3. Problem description:

VIM (Vi IMproved) is a version of the vi editor.  
 
VIM allows a user to set the modeline differently for each edited text 
file by placing special comments in the files.  Georgi Guninski found that
these comments can be carefully crafted in order to call external programs.
 This could allow an attacker to create a text file such that when it is
opened arbitrary commands are executed.   

Users of VIM are advised to upgrade to these errata packages which have 
been patched to disable the usage of dangerous functions in modelines.

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.
