CVE-2020-6800 – Mozilla: Memory safety bugs fixed in Firefox 73 and Firefox ESR 68.5
https://notcve.org/view.php?id=CVE-2020-6800
Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. 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. In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. Los desarrolladores de Mozilla y los miembros de comunidad han reportado bugs de seguridad de la memoria presentes en Firefox versión 72 y Firefox ESR versión 68.4. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1595786%2C1596706%2C1598543%2C1604851%2C1608580%2C1608785%2C1605777 https://security.gentoo.org/glsa/202003-02 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4278-2 https://usn.ubuntu.com/4328-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2020-05 https://www.mozilla.org/security/advisories/mfsa2020-06 https://www.mozilla.org/security/advisories/mfsa2020-07 https://access.redhat.com • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

CVE-2019-19921 – runc: volume mount race condition with shared mounts leads to information leak/integrity manipulation
https://notcve.org/view.php?id=CVE-2019-19921
runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.) runc versiones hasta 1.0.0-rc9, posee un Control de Acceso Incorrecto conllevando a una escalada de privilegios, relacionado con el archivo libcontainer/rootfs_linux.go. Para explotar esto, un atacante debe ser capaz de generar dos contenedores con configuraciones de montaje de volumen personalizadas y ser capaz de ejecutar imágenes personalizadas.

CVE-2020-1700
https://notcve.org/view.php?id=CVE-2020-1700
A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects. An authenticated attacker can abuse this flaw by making multiple disconnect attempts resulting in a permanent leak of a socket connection by radosgw. This flaw could lead to a denial of service condition by pile up of CLOSE_WAIT sockets, eventually leading to the exhaustion of available resources, preventing legitimate users from connecting to the system. Se encontró un fallo en la manera en que el front-end Ceph RGW Beast maneja desconexiones inesperadas.
