Hiya,
The patch only applies to ldm-users who are running pqsurf. The problem
was the processing of the short NIL type bulletins that caused buffer
overflow. Of course, the patch will be included in the next minor version
of the LDM that will be released soon.
To get the code:
The surf_split.c file is located in the ftp directory under
pub/ldm5
To install the code:
Copy the surf_split.c into the src/pqsurf directory
type:
% cd src/pqsurf
% make
% cp pqsurf ../../bin
stop/start the ldm.
For users of of the patch program the follow patch is included for
surf_split.c.
