https://notcve.org/view.php?id=CVE-2024-25003
KiTTY versions 0.76.1.13 and before is vulnerable to a stack-based buffer overflow via the hostname, occurs due to insufficient bounds checking and input sanitization. This allows an attacker to overwrite adjacent memory, which leads to arbitrary code execution. Las versiones de KiTTY 0.76.1.13 y anteriores son vulnerables a un desbordamiento de búfer en la región stack de la memoria a través del nombre de host, que se produce debido a una verificación de los límites y una sanitización de entrada insuficientes. Esto permite a un atacante sobrescribir la memoria adyacente, lo que conduce a la ejecución de código arbitrario. • https://www.exploit-db.com/exploits/51890 http://packetstormsecurity.com/files/177031/KiTTY-0.76.1.13-Command-Injection.html http://packetstormsecurity.com/files/177032/KiTTY-0.76.1.13-Buffer-Overflows.html http://seclists.org/fulldisclosure/2024/Feb/13 http://seclists.org/fulldisclosure/2024/Feb/14 https://blog.defcesco.io/CVE-2024-25003-CVE-2024-25004 • CWE-787: Out-of-bounds Write •

KiTTY versions 0.76.1.13 and before is vulnerable to command injection via the filename variable, occurs due to insufficient input sanitization and validation, failure to escape special characters, and insecure system calls (at lines 2369-2390). This allows an attacker to add inputs inside the filename variable, leading to arbitrary code execution. Las versiones de KiTTY 0.76.1.13 y anteriores son vulnerables a la inyección de comandos a través de la variable de nombre de archivo, se produce debido a una sanitización y validación de entrada insuficientes, no se pueden escapar caracteres especiales y llamadas inseguras al sistema (en las líneas 2369-2390). Esto permite a un atacante agregar entradas dentro de la variable de nombre de archivo, lo que lleva a la ejecución de código arbitrario.

CVSS: 5.9EPSS: 96%CPEs: 79EXPL: 1CVE-2023-48795 – ssh: Prefix truncation attack on Binary Packet Protocol (BPP)
https://notcve.org/view.php?id=CVE-2023-48795
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.

https://notcve.org/view.php?id=CVE-2022-41322
In Kitty before 0.26.2, insufficient validation in the desktop notification escape sequence can lead to arbitrary code execution. The user must display attacker-controlled content in the terminal, then click on a notification popup. En Kitty versiones anteriores a 0.26.2, una comprobación insuficiente en la secuencia de escape de la notificación de escritorio puede conllevar a una ejecución de código arbitrario. El usuario debe mostrar contenido controlado por el atacante en el terminal y luego hacer clic en una ventana emergente de notificación. • https://bugs.gentoo.org/868543 https://github.com/kovidgoyal/kitty/commit/f05783e64d5fa62e1aed603e8d69aced5e49824f https://github.com/kovidgoyal/kitty/compare/v0.26.1...v0.26.2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/47RK7MBSVY5BWDUTYMJUFPBAYFSWMTOI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6RRNAPU33PHEH64P77YL3AJO6CTZGHTX https://security.gentoo.org/glsa/202209-22 https://sw.kovidgoyal.net/kitty/changelog/#detailed-list&# • CWE-116: Improper Encoding or Escaping of Output •
