Bash Version: 3.2
Patch Level: 9
Release Status: release
Description:
I am trying to patch bash to have it open server sockets. While I
was debugging I found a problem with tcp sockets also present in the
unmodified bash. bash does not seem to notice that an opened
/dev/tcp/$host/$port file descriptor becomes invalid if the
connection is closed on the other end.
Repeat-By:
1. Open a second console and execute "netcat -l -p 5000"
2. switch back to first console
3. exec 5<>/dev/tcp/localhost/5000
4. echo "Hello World" >&5
5. switch to second console and hit <CTRL-C>
6. switch back to first console
7. echo "Hello World" >&5
8. echo "Hello World" >&5
bash has died
