The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0…

XLPD v7.0.0094 and below contains an unquoted service path vulnerability which allows local users to launch processes with elevated privileges.

Xshell v7.0.0099 and below contains a binary hijack vulnerability which allows attackers to execute arbitrary code via a crafted .exe file.

Xlpd v7.0.0094 and below contains a binary hijack vulnerability which allows attackers to execute arbitrary code via a crafted .exe file.

Xmanager v7.0.0096 and below contains a binary hijack vulnerability which allows attackers to execute arbitrary code via a crafted .exe file.

Xftp 7.0.0088p and below contains a binary hijack vulnerability which allows attackers to execute arbitrary code via a crafted .exe file.

Xshell before 7.0.0.76 allows attackers to cause a crash by triggering rapid changes to the title bar.

NetSarang Xshell 7 before Build 0077 includes unintended code strings in paste operations.

NetSarang XFTP Client 6.0149 and earlier version contains a buffer overflow vulnerability caused by improper boundary checks when copying file name from an attacker controlled FTP server. That leads attacker to execute arbitrary code by sending a crafted filename.

NetSarang Xlpd 4 Build 0100 and NetSarang Xmanager Enterprise 4 Build 0186 allow remote attackers to cause a denial of service (daemon crash) via a malformed LPD request.
