I'm using libssh2 from git. My test uses curl and if I try to establish a sftp session the program dies with "Segmentaion fault".
curl --insecure -u agebert:password --verbose sftp://gebert4.e2e.ch/ * About to connect() to gebert4.e2e.ch port 22 (#0) * Trying 127.0.0.2... connected * Connected to gebert4.e2e.ch (127.0.0.2) port 22 (#0) * SSH authentication methods available: publickey,gssapi-with-mic,keyboard-interactive * Using ssh public key file /home/agebert/.ssh/id_dsa.pub * Using ssh private key file /home/agebert/.ssh/id_dsa * SSH public key authentication failed: Unable to open public key file Segmentation fault Program received signal SIGSEGV, Segmentation fault. 0xb7cd8fa1 in free () from /lib/libc.so.6 (gdb) where #0 0xb7cd8fa1 in free () from /lib/libc.so.6 #1 0xb7e83670 in my_libssh2_free () from /home/agebert/local/lib/libcurl.so.4 #2 0xb7b136d8 in userauth_keyboard_interactive (session=0x8084a40, username=0x8084810 "agebert", username_len=7, response_callback=0xb7e83840 <kbd_callback>) at userauth.c:1616 #3 0xb7b1390b in libssh2_userauth_keyboard_interactive_ex (session=0x8084a40, user=0x8084810 "agebert", user_len=7, response_callback=0xb7e83840 <kbd_callback>) at userauth.c:1672 #4 0xb7e851d6 in ssh_statemach_act () from /home/agebert/local/lib/libcurl.so.4 #5 0xb7e87a32 in ssh_easy_statemach () from /home/agebert/local/lib/libcurl.so.4 #6 0xffffffff in ?? () I tried to isolate which commit introduced the regression. This is fine: 0723dab4d76c16208132367922ca2151cb458073 libssh2_channel_process_startup.3: clean up This does crash: 5b004a4b67e3c6e8de97d5bbbab470b1191b1a16 keyb-interactive: add the fixed buffer The other commits between these commits do not compile. For me the fix "keyb-interactive: allow zero length fields" is important because on AIX malloc(0) returns an error. If you need more details let me know.
