Thanks for reporting this! Most of the issues were related to buffer overflows, the curse of the C language. After fixing them I ran all the input files from your repo. There seems to be no crashes anymore, so I'm closing this.
Hello, I was using American Fuzzy Lop (afl-fuzz) to fuzz input to the
tcl
program on Linux. Is fixing the crashes from these input files something you're interested in? The input files can be found here: https://github.com/rwhitworth/partcl-fuzz/tree/master/2017-06-06The files can be executed as
./tcl id_filename
to cause the issues. This was tested against git commit 2f03722Let me know if I can provide any more information to help narrow down this issue.
