CVSS: 8.8EPSS: 96%CPEs: 68EXPL: 3CVE-2019-0211 – Apache HTTP Server Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-0211
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected. En Apache HTTP Server 2.4, versiones 2.4.17 a 2.4.38, con el evento MPM, worker o prefork, el código ejecutándose en procesos hijo (o hilos) menos privilegiados (incluyendo scripts ejecutados por un intérprete de scripts en proceso) podría ejecutar código arbitrario con los privilegios del proceso padre (normalmente root) manipulando el marcador. Los sistemas que no son Unix no se ven afectados. A flaw was found in Apache where code executing in a less-privileged child process or thread could execute arbitrary code with the privilege of the parent process (usually root). • https://www.exploit-db.com/exploits/46676 http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00084.html http://packetstormsecurity.com/files/152386/Apache-2.4.38-Root-Privilege-Escalation.html http://packetstormsecurity.com/files/152415/Slackware-Security-Advisory-httpd-Updates.html http://packetstormsecurity.com/files/152441/CARPE-DIEM-Apache-2.4.x • CWE-250: Execution with Unnecessary Privileges CWE-416: Use After Free •
CVSS: 7.0EPSS: 0%CPEs: 55EXPL: 1CVE-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 •
