Synopsis:          Updated vim packages fix modeline vulnerability
Advisory ID:       RHSA-2002:297-17
Issue date:        2003-01-16
Updated on:        2003-01-15

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.
