CVE-2018-5089 – Mozilla: Memory safety bugs fixed in Firefox 58 and Firefox ESR 52.6 (MFSA 2018-03)
https://notcve.org/view.php?id=CVE-2018-5089
Memory safety bugs were reported in Firefox 57 and Firefox ESR 52.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58. Se han informado de errores de seguridad de memoria en Firefox 57 y Firefox ESR 52.5.

CVE-2018-5095 – Mozilla: Integer overflow in Skia library during edge builder allocation (MFSA 2018-03)
https://notcve.org/view.php?id=CVE-2018-5095
An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 8 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58. Una vulnerabilidad de desbordamiento de enteros en la librería Skia cuando se asigna memoria para los "edge builders" en determinados sistemas con al menos 8 GB de RAM.

CVE-2018-5683 – Qemu: Out-of-bounds read in vga_draw_text routine
https://notcve.org/view.php?id=CVE-2018-5683
The vga_draw_text function in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging improper memory address validation. La función vga_draw_text en Qemu permite que usuarios del sistema operativo invitados con privilegios provoquen una denegación de servicio (acceso de lectura fuera de límites y cierre inesperado del proceso Qemu) aprovechando la validación indebida de direcciones de memoria. An out-of-bounds read access issue was found in the VGA emulator of QEMU. It could occur in vga_draw_text routine, while updating display area for a vnc client. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS. • http://www.openwall.com/lists/oss-security/2018/01/15/2 http://www.securityfocus.com/bid/102518 https://access.redhat.com/errata/RHSA-2018:0816 https://access.redhat.com/errata/RHSA-2018:1104 https://access.redhat.com/errata/RHSA-2018:2162 https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https://lists.gnu.org/archive/html/qemu-devel/2018-01/msg02597.html https://usn.ubuntu.com/3575-1 https://www.debian.org/security/2018/dsa-4213 https:/ • CWE-125: Out-of-bounds Read •
