Changelog:
These features are new in 0.76 (released 2021-07-17):
New option to abandon an SSH connection if the server allows you to authenticate in a trivial manner.
Bug fix: Windows PuTTY crashed when the 'Use system colours' option was used.
Bug fix: crash on Windows when using MIT Kerberos together with 'Restart Session'.
Bug fix: Windows PuTTY leaked named pipes after contacting Pageant.
Bug fix: Windows PuTTY didn't update the window while you held down the scrollbar arrow buttons long enough to 'key-repeat'.
Bug fix: user colour-palette reconfiguration via 'Change Settings' were delayed-action.
Bug fix: server colour-palette reconfigurations were sometimes lost.
Bug fix: a tight loop could occur on reading a truncated private key file.
Bug fix: the Windows Pageant GUI key list didn't display key lengths.
These features were new in 0.75 (released 2021-05-08):
Security fix: on Windows, a server could DoS the whole Windows GUI by telling the PuTTY window to change its title repeatedly at high speed.
Pageant now supports loading a key still encrypted, and decrypting it later by prompting for the passphrase on first use.
Upgraded default SSH key fingerprint format to OpenSSH-style SHA-256.
Upgraded private key file format to PPK3, with improved passphrase hashing and no use of SHA-1.
Terminal now supports ESC [ 9 m for strikethrough text.
New protocols: bare ssh-connection layer for use over already-secure IPC channels, and SUPDUP for talking to very old systems such as PDP-10s.
PuTTYgen now supports alternative provable-prime generation algorithm for RSA and DSA.
The Unix tools can now connect directly to a Unix-domain socket.
Changelog:
This release fixes the following security issues:
- In some situations an SSH server could cause PuTTY to access freed
mdmory by pretending to accept an SSH key and then refusing the
actual signature. It can only happen if you're using an SSH agent.
- New configuration option to disable PuTTY's default policy of
changing its host key algorithm preferences to prefer keys it
already knows. (There is a theoretical information leak in this
policy.)
Other bug fixes include:
- Windows installer: the text in the installer UI is now visible in
Windows high-contrast mode. (Previously it was white on white by
mistake.)
- Windows 7: fixed spurious OS out-of-memory error when reading
passwords from a Windows console (e.g. psftp).
- Terminal crash: the dreaded "line==NULL" error could happen if an
application switched between the main and alternate screens while
the user was looking at the scrollback.
- Terminal crash: the terminal could fail an assertion when sending
an empty answerback string, and when pasting text none of whose
characters exist in the selected character set.
- SSH: fixed endless memory-allocating loop that could be triggered
by the combination of a misbehaving SSH agent and PuTTY's bug
compatibility mode for padded RSA signatures.
- File transfer: when uploading files to some SFTP servers (e.g. the
one in proftpd's mod_sftp), PSFTP would consume up to 4GB of local
memory before sending anything to the server.
- Terminal behaviour: sometimes the cursor was put in the wrong place
after restoring from the alternate screen.
- GTK: fixed font size calculation when using newer Pango libraries
(e.g. the one on Ubuntu 20.04).
- GTK: scroll wheel events now work in unusual environments like VNC.
Changelog:
Vulnerabilities fixed in this release include:
- On Windows, the listening sockets used for local port forwarding
were opened in a mode that did not prevent other processes from
also listening on the same ports and stealing some of the incoming
connections.
- In the PuTTY terminal, bracketed paste mode was broken in 0.72, in
a way that made the pasted data look like manual keyboard input. So
any application relying on the bracketing sequences to protect
against malicious clipboard contents would have been misled.
- An SSH-1 server could trigger an access to freed memory by sending
the SSH1_MSG_DISCONNECT message. Not known to be exploitable.
Other bug fixes include:
- Windows Plink no longer crashes on startup when it tries to tell
you it's reusing an existing SSH connection.
- Windows PuTTY now updates its terminal window size correctly if the
screen resolution changes while it's maximised.
- If you display the coloured error messages from gcc in the PuTTY
terminal, there is no longer a missing character if a colour change
happens exactly at the end of a line.
- If you use the 'Clear Scrollback' menu option or escape sequence
while text in the scrollback is selected, it no longer causes an
assertion failure.
Changelog:
This is a SECURITY UPDATE, fixing vulnerabilities in the obsolete SSH-1
protocol. It also includes many bug fixes over 0.71. We recommend that
everybody update.
Vulnerabilities fixed in this release include:
- A malicious SSH-1 server could trigger a buffer overrun by sending
extremely short RSA keys, or certain bad packet length fields.
Either of these could happen before host key verification, so even
if you trust the server you *intended* to connect to, you would
still be at risk.
(However, the SSH-1 protocol is obsolete, and recent versions of
PuTTY do not try it by default, so you are only at risk if you work
with old servers and have explicitly configured SSH-1.)
- If a malicious process found a way to impersonate Pageant, then it
could cause an integer overflow in any of the SSH client tools
(PuTTY, Plink, PSCP, PSFTP) which accessed the malicious Pageant.
Other security-related bug fixes include:
- The 'trust sigil' system introduced in PuTTY 0.71 to protect
against server spoofing attacks had multiple bugs. Trust sigils
were not turned off after login in the SSH-1 and Rlogin protocols,
and not turned back on if you used the Restart Session command.
Both are now fixed.
Other bug fixes include:
- Kerberos key exchange could crash at the start of an SSH session
in the presence of a third-party Windows provider such as
MIT Kerberos for Windows, and could also crash if the server sent
an ordinary SSH host key as part of the Kerberos exchange.
- In SSH-2 keyboard-interactive authentication, one of the message
fields sent by the server (namely the 'instructions' message) was
accidentally never displayed to the user.
- When using SSH-2 connection sharing, pasting text into a downstream
PuTTY window that included a line longer than 16Kb could cause that
window's connection to be closed.
- When using PSCP in old-fashioned SCP mode, downloading files
specified by a wildcard could cause a newline character to be
appended to the downloaded file names. Also, using the -p option to
preserve file times failed with a spurious error message.
- On Windows, the numeric keypad key that should generate '.' or ','
depending on keyboard layout was always generating '.'.
- RSA keys generated by PuTTYgen could be 1 bit shorter than
requested. (Harmless, but a regression in 0.71 compared to 0.70.)
Changelog:
These features were new in 0.70 (released 2017-07-08):
Security fix: the Windows PuTTY binaries should no longer be
vulnerable to hijacking by specially named DLLs in the same
directory, even a name we missed when we thought we'd fixed
this in 0.69. See vuln-indirect-dll-hijack-3.
Windows PuTTY should be able to print again, after our DLL
hijacking defences broke that functionality.
Windows PuTTY should be able to accept keyboard input outside
the current code page, after our DLL hijacking defences broke
that too.
These features are new in 0.71 (released 2019-03-16):
Security fixes found by an EU-funded bug bounty programme:
a remotely triggerable memory overwrite in RSA key exchange,
which can occur before host key verification
potential recycling of random numbers used in cryptography
on Windows, hijacking by a malicious help file in the same
directory as the executable
on Unix, remotely triggerable buffer overflow in any kind
of server-to-client forwarding
multiple denial-of-service attacks that can be triggered
by writing to the terminal
Other security enhancements: major rewrite of the crypto code
to remove cache and timing side channels.
User interface changes to protect against fake authentication
prompts from a malicious server.
We now provide pre-built binaries for Windows on Arm.
Hardware-accelerated versions of the most common cryptographic
primitives: AES, SHA-256, SHA-1.
GTK PuTTY now supports non-X11 displays (e.g. Wayland) and
high-DPI configurations.
Type-ahead now works as soon as a PuTTY window is opened:
keystrokes typed before authentication has finished will be
buffered instead of being dropped.
Support for GSSAPI key exchange: an alternative to the older
GSSAPI authentication system which can keep your forwarded
Kerberos credentials updated during a long session.
More choices of user interface for clipboard handling.
New terminal features: support the REP escape sequence (fixing
an ncurses screen redraw failure), true colour, and SGR 2 dim
text.
Pressing Ctrl+Shift+PgUp or Ctrl+Shift+PgDn now takes you
straight to the top or bottom of the terminal scrollback.
* Convert to use GTK 3 to fix build
Changelog:
These features are new in 0.69 (released 2017-04-29):
Security fix: the Windows PuTTY binaries should no longer be vulnerable to hijacking by specially named DLLs in the same directory, even the names we missed when we thought we'd fixed this in 0.68. See vuln-indirect-dll-hijack-2.
Windows PuTTY should work with MIT Kerberos again, after our DLL hijacking defences broke it.
Jump lists should now appear again on the PuTTY shortcut in the Windows Start Menu.
You can now explicitly configure SSH terminal mode settings not to be sent to the server, if your server objects to them.
PuTTY 0.68, released today, supports elliptic-curve cryptography for host
keys, user authentication keys, and key exchange. Also, for the first time,
it comes in a 64-bit Windows version.
This update may create a build issue for non-BSD due to ancient functions
being different on BSD and SYSV. there's always macros if this fails.
Changelog: 2016-03-05 PuTTY 0.67 released, fixing a SECURITY HOLE
PuTTY 0.67, released today, fixes a security hole in 0.66 and
before: vuln-pscp-sink-sscanf. It also contains a few other small
bug fixes.
Also, for the first time, the Windows executables in this release
(including the installer) are signed using an Authenticode certificate,
to help protect against tampering in transit from our website or
after downloading. You should find that they list "Simon Tatham"
as the verified publisher.
Changelog:
2015-11-07 PuTTY 0.66 released, fixing a SECURITY HOLE
PuTTY 0.66, released today, fixes a security hole in 0.65 and before:
vuln-ech-overflow. It also contains a few other small bug fixes and minor
features.
Problems found locating distfiles:

Changelog:
2015-02-28 PuTTY 0.64 released, fixing a SECURITY HOLE
PuTTY 0.64, released today, fixes a security hole in 0.63 and before:
private-key-not-wiped-2. Also diffie-hellman-range-check has been argued
to be a security hole. In addition to these and other less critical bug
fixes, 0.64 also supports the major new feature of sharing an SSH connection
between multiple instances of PuTTY and its tools, and a command-line and
config option to specify the expected host key(s).
This fixes a buffer overflow which was patched in pkgsrc (CVE-2013-4852),
two other buffer overflows (CVE-2013-4206, CVE-2013-4207), and
it clears private keys after use now (CVE-2013-4208).
Other than that, there are mostly bug fixes from 0.62 and a few
small features.
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
