CVE-2019-6454 – systemd: Insufficient input validation in bus_process_object() resulting in PID 1 crash
https://notcve.org/view.php?id=CVE-2019-6454
An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic). Se ha descubierto un problema en sd-bus en systemd 239. bus_process_object() en libsystemd/sd-bus/bus-objects.c asigna un búfer de pila de longitud variable para almacenar temporalmente la ruta de objeto de los mensajes D-Bus entrantes. Un usuario local sin privilegios puede explotar esto enviando un mensaje especialmente manipulado a PID1, provocando que el puntero de la pila salte por las páginas guard de la pila hasta una región de memoria no mapeada y desencadene una denegación de servicio (cierre inesperado del PID1 en systemd y pánico del kernel). It was discovered that systemd allocates a buffer large enough to store the path field of a dbus message without performing enough checks. • http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00070.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00062.html http://www.openwall.com/lists/oss-security/2019/02/18/3 http://www.openwall.com/lists/oss-security/2019/02/19/1 http://www.openwall.com/lists/oss-security/2021/07/20/2 http://www.securityfocus.com/bid/107081 https://access.redhat.com/errata/RHSA-2019:0368 https://access.redhat.com/errata/RHSA-2019:0990 https://access • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •
CVE-2016-3715 – ImageMagick Arbitrary File Deletion Vulnerability
https://notcve.org/view.php?id=CVE-2016-3715
The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image. El codificador EPHEMERAL en ImageMagick en versiones anteriores a 6.9.3-10 y 7.x en versiones anteriores a 7.0.1-1 permite a atacantes remotos eliminar archivos arbitrarios a través de una imagen manipulada. It was discovered that certain ImageMagick coders and pseudo-protocols did not properly prevent security sensitive operations when processing specially crafted images. A remote attacker could create a specially crafted image that, when processed by an application using ImageMagick or an unsuspecting user using the ImageMagick utilities, would allow the attacker to delete arbitrary files. ImageMagick contains an unspecified vulnerability that could allow users to delete files by using ImageMagick's 'ephemeral' pseudo protocol, which deletes files after reading. • https://www.exploit-db.com/exploits/39767 http://git.imagemagick.org/repos/ImageMagick/blob/a01518e08c840577cabd7d3ff291a9ba735f7276/ChangeLog http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00051.html http • CWE-20: Improper Input Validation •
CVE-2016-3718 – ImageMagick Server-Side Request Forgery (SSRF) Vulnerability
https://notcve.org/view.php?id=CVE-2016-3718
The (1) HTTP and (2) FTP coders in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allow remote attackers to conduct server-side request forgery (SSRF) attacks via a crafted image. Los codificadores (1) HTTP y (2) FTP en ImageMagick en versiones anteriores a 6.9.3-10 y 7.x en versiones anteriores a 7.0.1-1 permiten a atacantes remotos llevar a cabo ataques de falsificación de peticiones del lado del servidor (SSRF) a través de una imagen manipulada. A server-side request forgery flaw was discovered in the way ImageMagick processed certain images. A remote attacker could exploit this flaw to mislead an application using ImageMagick or an unsuspecting user using the ImageMagick utilities into, for example, performing HTTP(S) requests or opening FTP sessions via specially crafted images. ImageMagick contains an unspecified vulnerability that allows attackers to perform server-side request forgery (SSRF) via a crafted image. • https://www.exploit-db.com/exploits/39767 http://git.imagemagick.org/repos/ImageMagick/blob/a01518e08c840577cabd7d3ff291a9ba735f7276/ChangeLog http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00051.html http • CWE-352: Cross-Site Request Forgery (CSRF) CWE-918: Server-Side Request Forgery (SSRF) •
CVE-2014-7169 – GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-7169
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. GNU Bash hasta 4.3 bash43-025 procesa cadenas finales después de la definición malformada de funciones en los valores de variables de entorno, lo que permite a atacantes remotos escribir hacia ficheros o posiblemente tener otro impacto desconocido a través de un entorno manipulado, tal y como se ha demostrado por vectores que involucran la característica ForceCommand en sshd OpenSSH, los módulos mod_cgi y mod_cgid en el Apache HTTP Server, scripts ejecutados por clientes DHCP no especificados, y otras situaciones en la cual establecer el entorno ocurre a través de un límite privilegiado de la ejecución de Bash. Nota: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271. It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. • https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/34766 https://www.exploit-db.com/exploits/35115 https://www.exploit-db.com/exploits/36933 https://www.exploit-db.com/exploits/34765 https://www.exploit-db.com/exploits/34860 https://www.exploit-db.com/exploits/34879 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-228: Improper Handling of Syntactically Invalid Structure •
