CVSS: 4.6EPSS: 0%CPEs: 4EXPL: 0CVE-2018-19985 – kernel: oob memory read in hso_probe in drivers/net/usb/hso.c
https://notcve.org/view.php?id=CVE-2018-19985
The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds (OOB) read that potentially allows arbitrary read in the kernel address space. La función hso_get_config_data en drivers/net/usb/hso.c en el kernel de Linux, hasta la versión 4.19.8, lee if_num desde el dispositivo USB (como un u8) y lo emplea para indexar un array pequeño, lo que resulta en una lectura de objetos fuera de límites (OOB) que podría permitir la lectura arbitraria en el espacio de direcciones del kernel. A flaw was found in the Linux kernel in the function hso_probe() which reads if_num value from the USB device (as an u8) and uses it without a length check to index an array, resulting in an OOB memory read in hso_probe() or hso_get_config_data(). An attacker with a forged USB device and physical access to a system (needed to connect such a device) can cause a system crash and a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2019-01/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00007.html http://packetstormsecurity.com/files/151420/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://hexhive.epfl.ch/projects/perifuzz https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-an • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2018-16888
It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable. Se ha descubierto que systemd no comprueba correctamente el contenido de archivos PIDFile antes de emplearlo para terminar procesos. • https://access.redhat.com/errata/RHSA-2019:2091 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16888 https://lists.apache.org/thread.html/5960a34a524848cd722fd7ab7e2227eac10107b0f90d9d1e9c3caa74%40%3Cuser.cassandra.apache.org%3E https://security.netapp.com/advisory/ntap-20190307-0007 https://usn.ubuntu.com/4269-1 https://access.redhat.com/security/cve/CVE-2018-16888 https://bugzilla.redhat.com/show_bug.cgi?id=1662867 • CWE-250: Execution with Unnecessary Privileges CWE-269: Improper Privilege Management •

An out of bounds read was discovered in systemd-journald in the way it parses log messages that terminate with a colon ':'. A local attacker can use this flaw to disclose process memory data. Versions from v221 to v239 are vulnerable. Se ha descubierto una lectura fuera de límites en systemd-journald en la forma en la que analiza mensajes de registro que terminan con dos puntos ":".

https://notcve.org/view.php?id=CVE-2019-5489
The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. La implementación mincore() en mm/mincore.c en el kernel de Linux hasta la versión 4.19.13 permitía a los atacantes observar patrones de acceso a las páginas de caché de otros procesos en el mismo sistema, permitiendo el esnifado de información secreta.
