Description Josh Bressers 2005-07-26 15:27:04 UTC 
A bug was found in vim which can allow a malicious modeline to execute arbitrary
code.

The initial discovery is here:
http://www.guninski.com/where_do_you_want_billg_to_go_today_5.html

The fix for this issue seems to span two patchsets (the second fixes what the
first misses)

Comment 1 Josh Bressers 2005-07-26 15:28:28 UTC 
This issue should also affects RHEL2.1 and RHEL3
Comment 2 Karsten Hopp 2005-08-10 23:12:14 UTC 
I'm not sure about 2.1. Do you really want me to do an RHSA for 2.1 ?

Demo exploit for this issue

If you open this file with vim, it will create the file /tmp/vim-test-1.exec

I just verified it on RHEL2.1, so yes, we'll want to patch that as well.
