https://notcve.org/view.php?id=CVE-2018-20169
An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c. Se ha descubierto un problema en el kernel de Linux hasta antes de la versión 4.19.9. El subsistema USB gestiona de manera incorrecta las comprobaciones de tamaño durante la lectura de un descriptor extra, relacionado con __usb_get_extra_descriptor en drivers/usb/core/usb.c. A flaw was discovered in the Linux kernel's USB subsystem in the __usb_get_extra_descriptor() function in the drivers/usb/core/usb.c which mishandles a size check during the reading of an extra descriptor data. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=704620afc70cf47abb9d6a1a57f3825d2bca49cf https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.9 https://github.com/torvalds/linux/commit/704620afc70cf47abb9d6a1a57f3825d2bca49cf https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html https:/ • CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •

A flaw was found in qemu Media Transfer Protocol (MTP). The code opening files in usb_mtp_get_object and usb_mtp_get_partial_object and directories in usb_mtp_object_readdir doesn't consider that the underlying filesystem may have changed since the time lstat(2) was called in usb_mtp_object_alloc, a classical TOCTTOU problem. An attacker with write access to the host filesystem shared with a guest can use this property to navigate the host filesystem in the context of the QEMU process and read any file the QEMU process has access to. Access to the filesystem may be local or via a network share protocol such as CIFS. Se ha detectado un error en el protocolo MTP (Media Transfer Protocol) de QEMU. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html http://www.securityfocus.com/bid/106212 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16872 https://lists.debian.org/debian-lts-announce/2019/02/msg00041.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CGCFIFSIWUREEQQOZDZFBYKWZHXCWBZN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KJMTVGDLA654HNCDGLCUEIP36SNJEKK7 https://seclists.org/bugtraq/20 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

https://notcve.org/view.php?id=CVE-2018-18493
A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. Puede ocurrir un desbordamiento de búfer en la librería SKIA durante los cálculos de un desplazamiento de búfer con acciones de hardware aceleradas de CANVAS 2D, debido al uso de cálculos de 32-bit en vez de 64-bit.
