libssh2_org was updated to version 1.5.0 to fix bugs and a security issue.
Changes in 1.5.0: Added Windows Cryptography API: Next Generation based backend
Bug fixes :
Security Advisory: Using SSH_MSG_KEXINIT
data unbounded, CVE-2015-1782
missing _libssh2_error in _libssh2_channel_write
knownhost: Fix DSS keys being detected as unknown.
knownhost: Restore behaviour of libssh2_knownhost_writeline
with short buffer.
libssh2.h: on Windows, a socket is of type SOCKET, not int
libssh2_priv.h: a 1 bit bit-field should be unsigned
windows build: do not export externals from static library
Fixed two potential use-after-frees of the payload buffer
Fixed a few memory leaks in error paths
userauth: Fixed an attempt to free from stack on error
agent_list_identities: Fixed memory leak on OOM
knownhosts: Abort if the hosts buffer is too small
sftp_close_handle: ensure the handle is always closed
channel_close: Close the channel even in the case of errors
docs: added missing libssh2_session_handshake.3 file
docs: fixed a bunch of typos
userauth_password: pass on the underlying error code
_libssh2_channel_forward_cancel: accessed struct after free
_libssh2_packet_add: avoid using uninitialized memory
_libssh2_channel_forward_cancel: avoid memory leaks on error
_libssh2_channel_write: client spins on write when window full
windows build: fix build errors
publickey_packet_receive: avoid junk in returned pointers
channel_receive_window_adjust: store windows size always
userauth_hostbased_fromfile: zero assign to avoid uninitialized use
configure: change LIBS not LDFLAGS when checking for libs
agent_connect_unix: make sure there’s a trailing zero
MinGW build: Fixed redefine warnings.
sftpdir.c: added authentication method detection.
Watcom build: added support for WinCNG build.
configure.ac: replace AM_CONFIG_HEADER with AC_CONFIG_HEADERS
sftp_statvfs: fix for servers not supporting statfvs extension
knownhost.c: use LIBSSH2_FREE macro instead of free
Fixed compilation using mingw-w64
knownhost.c: fixed that ‘key_type_len’ may be used uninitialized
configure: Display individual crypto backends on separate lines
examples on Windows: check for WSAStartup return code
examples on Windows: check for socket return code
agent.c: check return code of MapViewOfFile
kex.c: fix possible NULL pointer de-reference with session->kex
packet.c: fix possible NULL pointer de-reference within listen_state
tests on Windows: check for WSAStartup return code
userauth.c: improve readability and clarity of for-loops
examples on Windows: use native SOCKET-type instead of int
packet.c: i < 256 was always true and i would overflow to 0
kex.c: make sure mlist is not set to NULL
session.c: check return value of session_nonblock in debug mode
session.c: check return value of session_nonblock during startup
userauth.c: make sure that sp_len is positive and avoid overflows
knownhost.c: fix use of uninitialized argument variable wrote
openssl: initialise the digest context before calling EVP_DigestInit()
libssh2_agent_init: init ->fd to LIBSSH2_INVALID_SOCKET
configure.ac: Add zlib to Requires.private in libssh2.pc if using zlib
configure.ac: Rework crypto library detection
configure.ac: Reorder --with-* options in --help output
configure.ac: Call zlib zlib and not libz in text but keep option names
Fix non-autotools builds: Always define the LIBSSH2_OPENSSL CPP macro
sftp: seek: Don’t flush buffers on same offset
sftp: statvfs: Along error path, reset the correct ‘state’ variable.
sftp: Add support for fsync (OpenSSH extension).
_libssh2_channel_read: fix data drop when out of window
comp_method_zlib_decomp: Improve buffer growing algorithm
_libssh2_channel_read: Honour window_size_initial
window_size: redid window handling for flow control reasons
knownhosts: handle unknown key types
