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-2018-18506 – Mozilla: Proxy Auto-Configuration file can define localhost access to be proxied
https://notcve.org/view.php?id=CVE-2018-18506
When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65. Cuando la autodetección del proxy está habilitada, si un servidor web proporciona un archivo de autoconfiguración de proxy (PAC) o si dicho archivo se carga localmente, este último puede especificar peticiones al host local que están destinadas a enviarse a través del proxy hacia otro servidor. Este comportamiento está prohibido por defecto cuando un proxy se configura manualmente. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00043.html http://www.securityfocus.com/bid/106773 https://access.redhat.com/errata/RHSA-2019:0622 https://access.redhat.com/errata/RHSA-2019:0623 https://access.redhat.com/errata/RHSA-2019:0680 https:/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
