smbc crashes due to buffer overflow

[michaël]

Binary package hint: smbc

On Ubuntu 8.10 Intrepid (32 bit)
smbc version: 1.2.2-3

Running the "smbc" causes it to fail due to a buffer overflow. The info it writes to STDOUT is in attachment.

It's not that important, but somebody might want to see the output in the "smbc.crash.output.txt" file where I redirect to as can be seen in the smbc.crash.output.stdout.txt file above.

This still occurs in Karmic. I have confirmed the bug; will attach a core momentarily.

Here's the core file; it was generated from gdb immediately after the program received SIGABRT.

I have gotten the software to build now such that it does not crash (it looks like the hardcoded -O3 and a missing header include directive in the main .c file might be responsible), but it does not exactly appear to work, either. It does appear that this program needs to be seriously cleaned up, though and that I have not the time for, unfortunately.

I had just installed smbc on ubuntu 9.10 and encountered the same results as shown in Michaels ...stdout.txt file.
