An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users can cause a denial of service (host OS hang) via a high rate of events to dom0, aka CID-e99502f76271. Se detectó un problema en el kernel de Linux versiones hasta 5.9.1, como es usado con Xen versiones hasta 4.14.x. Los usuarios del Sistema Operativo invitado pueden causar una denegación de servicio (suspensión del Sistema Operativo host) por medio de una alta tasa de eventos en dom0, también se conoce como CID-e99502f76271 • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00075.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00025.html http://www.openwall.com/lists/oss-security/2021/01/19/6 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e99502f76271d6bc4e374fe368c50c67a1fd3070 https://github.com/torvalds/linux/commit/e99502f76271d6bc4e374fe368c50c67a1fd3070 https://lists.debian.org/debian-lts-announce/2020/12/msg00015.html https://lists.debian.org/debian-lts-announ •
CVSS: 9.8EPSS: 1%CPEs: 7EXPL: 0CVE-2020-15683 – Mozilla: Memory safety bugs fixed in Firefox 82 and Firefox ESR 78.4
https://notcve.org/view.php?id=CVE-2020-15683
Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR 78.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.4, Firefox < 82, and Thunderbird < 78.4. Los desarrolladores de Mozilla y los miembros de la comunidad informaron bugs de seguridad de la memoria presentes en Firefox versión 81 y Firefox ESR versión 78.3. Algunos de estos bugs mostraron evidencia de corrupción de la memoria y suponemos que con suficiente esfuerzo algunos de ellos podrían haber sido explotados para ejecutar código arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00057.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00062.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00074.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00077.html https://bugzilla.mozilla.org/buglist.cgi?bug_id=1576843%2C1656987%2C1660954%2C1662760%2C1663439%2C1666140 https://lists.debian.org/debian-lts-announce/2020/10/msg00027.html https://security.gentoo.org/glsa/202010 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-416: Use After Free CWE-787: Out-of-bounds Write •

Vulnerability in the Java SE product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 11.0.8 and 15. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00041.html https://lists.debian.org/debian-lts-announce/2020/10/msg00031.html https://security.gentoo.org/glsa/202101-19 https://security.netapp.com/advisory/ntap-20201023-0004 https://www.debian.org/security/2020/dsa-4779 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020.html https://access.redhat.com/security/cve/CVE-2020-14803 https://bugzilla.redhat.com/show_bug& • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
