Summary: close() is called twice in confree()
Product: Portable OpenSSH
Version: 7.5p1
Hardware: Other

Status: NEW
Severity: minor

close() is called twice in confree()
Current code -
ssh_packet_close() internally calls the close() again.
confree(int s)
{
......
......
close(s);
......
......
if (fdcon[s].c_ssh) {
ssh_packet_close(fdcon[s].c_ssh);
......
......
}
Fix -
confree(int s)
{
......
......
if (fdcon[s].c_ssh) {
ssh_packet_close(fdcon[s].c_ssh);
free(fdcon[s].c_ssh);
fdcon[s].c_ssh = NULL;
} else
close(s);
......
......
}
