Description Josh Bressers 2005-03-16 14:24:22 EST
The vulnerability specifically exists in the handling of the LINEMODE
suboptions, in that there is no size check made on the output, which is stored
in a fixed length buffer. By sending a specially constructed reply containing a
large number of SLC (Set Local Character) commands, it is possible to overflow
this buffer with server supplied data.
