The remote FreeBSD host is missing a security-related update.
Ben Harris reports :
Versions of PuTTY and pterm between 0.54 and 0.65 inclusive have a
potentially memory-corrupting integer overflow in the handling of the
ECH (erase characters) control sequence in the terminal emulator.
To exploit a vulnerability in the terminal emulator, an attacker must
be able to insert a carefully crafted escape sequence into the
terminal stream. For a PuTTY SSH session, this must be before
encryption, so the attacker likely needs access to the server you're
connecting to. For instance, an attacker on a multi-user machine that
you connect to could trick you into running cat on a file they control
containing a malicious escape sequence. (Unix write(1) is not a vector
for this, if implemented correctly.)
Only PuTTY, PuTTYtel, and pterm are affected; other PuTTY tools do not
include the terminal emulator, so cannot be exploited this way.
