A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system. Se encontró una condición de ejecución en el multiplexor tty GSM 0710 en el kernel de Linux. Este problema ocurre cuando dos subprocesos ejecutan GSMIOC_SETCONF ioctl en el mismo descriptor de archivo tty con la disciplina de línea gsm habilitada y puede provocar un problema de use after free en una estructura gsm_dlci al reiniciar gsm mux. • http://www.openwall.com/lists/oss-security/2024/04/10/18 http://www.openwall.com/lists/oss-security/2024/04/10/21 http://www.openwall.com/lists/oss-security/2024/04/11/7 http://www.openwall.com/lists/oss-security/2024/04/11/9 http://www.openwall.com/lists/oss-security/2024/04/12/1 http://www.openwall.com/lists/oss-security/2024/04/12/2 http://www.openwall.com/lists/oss-security/2024/04/16/2 http://www.openwall.com/lists/oss-security/20 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

A flaw was found in the libssh implements abstract layer for message digest (MD) operations implemented by different supported crypto backends. The return values from these were not properly checked, which could cause low-memory situations failures, NULL dereferences, crashes, or usage of the uninitialized memory as an input for the KDF. In this case, non-matching keys will result in decryption/integrity failures, terminating the connection. Se encontró un fallo en la capa abstracta de implementación de libssh para operaciones de resumen de mensajes (MD) implementadas por diferentes backends criptográficos compatibles. Los valores de retorno de estos no se verificaron correctamente, lo que podría causar fallas en situaciones de poca memoria, desreferencias NULL, fallas o uso de la memoria no inicializada como entrada para el KDF. • https://access.redhat.com/errata/RHSA-2024:2504 https://access.redhat.com/errata/RHSA-2024:3233 https://access.redhat.com/security/cve/CVE-2023-6918 https://bugzilla.redhat.com/show_bug.cgi?id=2254997 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LZQVUHWVWRH73YBXUQJOD6CKHDQBU3DM https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MKQRBF3DWMWPH36LBCOBUTSIZRTPEZXB https://www.libssh.org/2023/12/18/libssh-0-10-6-and-libssh- • CWE-252: Unchecked Return Value •

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.

A template injection flaw was found in Ansible where a user's controller internal templating operations may remove the unsafe designation from template data. This issue could allow an attacker to use a specially crafted file to introduce templating injection when supplying templating data. Se encontró una falla de inyección de plantilla en Ansible donde las operaciones de creación de plantillas internas del controlador de un usuario pueden eliminar la designación insegura de los datos de la plantilla. Este problema podría permitir que un atacante utilice un archivo especialmente manipulado para introducir la inyección de código al proporcionar datos de plantillas. • https://access.redhat.com/errata/RHSA-2023:7773 https://access.redhat.com/security/cve/CVE-2023-5764 https://bugzilla.redhat.com/show_bug.cgi?id=2247629 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/X7Q6CHPVCHMZS5M7V22GOKFSXZAQ24EU • CWE-1336: Improper Neutralization of Special Elements Used in a Template Engine •
