In /drivers/isdn/i4l/isdn_net.c: A user-controlled buffer is copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow. This affects the Linux kernel 4.9-stable tree, 4.12-stable tree, 3.18-stable tree, and 4.4-stable tree. Una inyección de comandos en transferencias desde otro servidor en extplorer en se versiones 2.1.9 y anteriores permite que un atacante inyecte comandos a través del parámetro userfile[0]. • http://www.openwall.com/lists/oss-security/2020/02/11/1 http://www.openwall.com/lists/oss-security/2020/02/11/2 http://www.openwall.com/lists/oss-security/2020/02/14/4 http://www.securityfocus.com/bid/100251 https://patchwork.kernel.org/patch/9880041 https://usn.ubuntu.com/3620-1 https://usn.ubuntu.com/3620-2 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used. libgcrypt en versiones anteriores a la 1.7.8 es vulnerable a un ataque de canal lateral de memoria caché, resultando en una brecha completa de RSA-1024 cuando se utiliza un método left-to-right para procesar la expansión de la ventana deslizante. Se cree que el mismo ataque funciona en RSA-2048 con un nivel de procesamiento moderadamente mayor. Este canal lateral necesita que el atacante pueda ejecutar software arbitrario en el hardware en donde se utiliza la clave privada RSA. • http://www.securityfocus.com/bid/99338 http://www.securitytracker.com/id/1038915 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-7526 https://eprint.iacr.org/2017/627 https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git%3Ba=commit%3Bh=78130828e9a140a9de4dafadbc844dbb64cb709a https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git%3Ba=commit%3Bh=8725c99ffa41778f382ca97233183bcd687bb0ce https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git%3Ba=commit%3Bh=e6a3dc9900433bbc8ad362a595a3837318c28fa9 https: • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2017-6519
avahi-daemon in Avahi through 0.6.32 and 0.7 inadvertently responds to IPv6 unicast queries with source addresses that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) and may cause information leakage by obtaining potentially sensitive information from the responding device via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809. avahi-daemon en Avahi, hasta las versiones 0.6.32 y 0.7, responde a consultas IPv6 unicast arbitrarias de manera inadvertida con direcciones de origen que no se pueden resolver localmente, lo que permite a los atacantes remotos provocar una denegación de servicio (amplificación de tráfico) y puede conducir a una fuga de información, obteniendo información potencialmente sensible del dispositivo de respuesta mediante paquetes UDP del puerto 5353.

https://notcve.org/view.php?id=CVE-2017-7889
The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c. El subsistema mm en el kernel de Linux hasta la versión 3.2 no aplica adecuadamente el mecanismo de protección CONFIG_STRICT_DEVMEM, lo que permite a usuarios locales leer o escribir en ubicaciones de la memoria del kernel en el primer megabyte (y eludir restricciones de acceso de asignación de slab) a través de una aplicación que abre el archivo /dev/mem, relacionado con arch/x86/mm/init.c y drivers/char/mem.c The mm subsystem in the Linux kernel through 4.10.10 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a4866aa812518ed1a37d8ea0c881dc946409de94 http://www.debian.org/security/2017/dsa-3945 http://www.openwall.com/lists/oss-security/2017/04/16/4 http://www.securityfocus.com/bid/97690 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://access.redhat.com/errata/RHSA-2018:1854 https://git.kernel.org/pub/ • CWE-391: Unchecked Error Condition CWE-732: Incorrect Permission Assignment for Critical Resource •
