The remote host is missing an update to vim announced via advisory USN-505-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS Ubuntu 6.10 Ubuntu 7.04
This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.
Details follow:
Ulf Harnhammar discovered that vim does not properly sanitise the helptags_one() function when running the helptags command. By tricking a user into running a crafted help file, a remote attacker could execute arbitrary code with the user's privileges.
Solution: The problem can be corrected by upgrading your system to the following package versions:
Ubuntu 6.06 LTS: vim 1:6.4-006+2ubuntu6.1
Ubuntu 6.10: vim 1:7.0-035+1ubuntu5.2
Ubuntu 7.04: vim 1:7.0-164+1ubuntu7.2
In general, a standard system upgrade is sufficient to effect the necessary changes.
