CVE-2017-5470 – Mozilla: Memory safety bugs fixed in Firefox 54 and Firefox ESR 52.2 (MFSA 2017-16)
https://notcve.org/view.php?id=CVE-2017-5470
Memory safety bugs were reported in Firefox 53 and Firefox ESR 52.1. 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 Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2. Se han reportado errores de seguridad de memoria en Firefox 53 y Firefox ESR 52.1. Algunos de estos errores mostraron evidencias de corrupción de memoria y se entiende que, con el suficiente esfuerzo, algunos de estos podrían explotarse para ejecutar código arbitrario. • http://www.securityfocus.com/bid/99041 http://www.securitytracker.com/id/1038689 https://access.redhat.com/errata/RHSA-2017:1440 https://access.redhat.com/errata/RHSA-2017:1561 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1359639%2C1349595%2C1352295%2C1352556%2C1342552%2C1342567%2C1346012%2C1366140%2C1368732%2C1297111%2C1362590%2C1357462%2C1363280%2C1349266%2C1352093%2C1348424%2C1347748%2C1356025%2C1325513%2C1367692 https://www.debian.org/security/2017/dsa-3881 https://www.debian.org/security/2017/dsa-3918 https: • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-5472 – Mozilla: Use-after-free using destroyed node when regenerating trees (MFSA 2017-16)
https://notcve.org/view.php?id=CVE-2017-5472
A use-after-free vulnerability with the frameloader during tree reconstruction while regenerating CSS layout when attempting to use a node in the tree that no longer exists. This results in a potentially exploitable crash. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2. Vulnerabilidad de uso de memoria previamente liberada en el frameloader durante la reconstrucción de árboles cuando se regenera el diseño CSS al intentar emplear un nodo en el árbol que ya no existe. Esto resulta en un cierre inesperado potencialmente explotable. • http://www.securityfocus.com/bid/99040 http://www.securitytracker.com/id/1038689 https://access.redhat.com/errata/RHSA-2017:1440 https://access.redhat.com/errata/RHSA-2017:1561 https://bugzilla.mozilla.org/show_bug.cgi?id=1365602 https://www.debian.org/security/2017/dsa-3881 https://www.debian.org/security/2017/dsa-3918 https://www.mozilla.org/security/advisories/mfsa2017-15 https://www.mozilla.org/security/advisories/mfsa2017-16 https://www.mozilla.org/security/advisories • CWE-416: Use After Free •

CVE-2017-9462 – mercurial: Python debugger accessible to authorized users
https://notcve.org/view.php?id=CVE-2017-9462
In Mercurial before 4.1.3, "hg serve --stdio" allows remote authenticated users to launch the Python debugger, and consequently execute arbitrary code, by using --debugger as a repository name. En Mercurial, en versiones anteriores a la 4.1.3, \"hg serve --stdio\" permite que usuarios autenticados remotos inicien el depurador de Python y, como consecuencia, ejecuten código arbitrario utilizando --debugger como nombre del repositorio. A flaw was found in the way "hg serve --stdio" command in Mercurial handled command-line options. A remote, authenticated attacker could use this flaw to execute arbitrary code on the Mercurial server by using specially crafted command-line options. • http://www.debian.org/security/2017/dsa-3963 http://www.securityfocus.com/bid/99123 https://access.redhat.com/errata/RHSA-2017:1576 https://bugs.debian.org/861243 https://lists.debian.org/debian-lts-announce/2018/07/msg00005.html https://security.gentoo.org/glsa/201709-18 https://www.mercurial-scm.org/repo/hg/rev/77eaf9539499 https://www.mercurial-scm.org/wiki/WhatsNew#Mercurial_4.1.3_.282017-4-18.29 https://access.redhat.com/security/cve/CVE-2017-9462 https: • CWE-284: Improper Access Control CWE-732: Incorrect Permission Assignment for Critical Resource •
CVE-2017-7980 – Qemu: display: cirrus: OOB r/w access issues in bitblt routines
https://notcve.org/view.php?id=CVE-2017-7980
Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation. Desbordamiento de búfer basado en memoria dinámica (heap) en Cirrus CLGD 54xx VGA Emulator en Quick Emulator (Qemu) en versiones 2.8 y anteriores permite que los usuarios invitados del sistema operativo ejecuten código arbitrario o provoquen una denegación de servicio (DoS) mediante vectores relacionados con un cliente VNC que actualiza su display después de una operación VGA. An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. • http://ubuntu.com/usn/usn-3289-1 http://www.openwall.com/lists/oss-security/2017/04/21/1 http://www.securityfocus.com/bid/102129 http://www.securityfocus.com/bid/97955 https://access.redhat.com/errata/RHSA-2017:0980 https://access.redhat.com/errata/RHSA-2017:0981 https://access.redhat.com/errata/RHSA-2017:0982 https://access.redhat.com/errata/RHSA-2017:0983 https://access.redhat.com/errata/RHSA-2017:0984 https://access.redhat.com/errata/RHSA-2017:0988 https • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
