Package : xterm
Vulnerability : design flaw
Problem type : local (remote)
Debian-specific: no

As an additional precaution, this security update also disables font

sequences.

For the stable distribution (etch), this problem has been fixed in
version 222-1etch3.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your xterm package.
