https://notcve.org/view.php?id=CVE-2020-17489
An issue was discovered in certain configurations of GNOME gnome-shell through 3.36.4. When logging out of an account, the password box from the login dialog reappears with the password still visible. If the user had decided to have the password shown in cleartext at login time, it is then visible for a brief moment upon a logout. (If the password were never shown in cleartext, only the password length is revealed.) Se detectó un problema en determinadas configuraciones de GNOME gnome-shell versiones hasta 3.36.4. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00028.html https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2997 https://lists.debian.org/debian-lts-announce/2020/09/msg00014.html https://security.gentoo.org/glsa/202009-08 https://usn.ubuntu.com/4464-1 https://access.redhat.com/security/cve/CVE-2020-17489 https://bugzilla.redhat.com/show_bug.cgi?id=1868418 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-522: Insufficiently Protected Credentials •

https://notcve.org/view.php?id=CVE-2020-16092
In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in hw/net/net_tx_pkt.c. En QEMU versiones hasta 5.0.0, puede ocurrir un fallo de aserción en el procesamiento de paquetes de red. Este problema afecta a los dispositivos de red e1000e y vmxnet3. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00024.html http://www.openwall.com/lists/oss-security/2020/08/10/1 https://lists.debian.org/debian-lts-announce/2020/09/msg00013.html https://lists.nongnu.org/archive/html/qemu-devel/2020-07/msg07563.html https://security.gentoo.org/glsa/202208-27 https://security.netapp.com/advisory/ntap-20200821-0006 https://usn.ubuntu.com/4467-1 https://www.debian.org/security/2020/dsa-4760 https://access.redhat.com/s • CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2020-15658
The code for downloading files did not properly take care of special characters, which led to an attacker being able to cut off the file ending at an earlier position, leading to a different file type being downloaded than shown in the dialog. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. El código para descargar archivos no toma cuidado apropiadamente de los caracteres especiales, lo que conllevaba a que un atacante sea capaz de cortar el archivo que terminaba en una posición anterior, conllevando a que sea descargado un tipo de archivo diferente al mostrado en el cuadro de diálogo. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 78.1, Firefox versiones anteriores a 79 y Thunderbird versiones anteriores a 78.1 • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html https://bugzilla.mozilla.org/show_bug.cgi?id=1637745 https://usn.ubuntu.com/4443-1 https://www.mozilla.org/security/advisories/mfsa2020-30 https://www.mozilla.org/security/advisories/mfsa2020-32 https://www.mozilla.org/security/advisories/mfsa2020-33 https://access.redhat.com/security/cve/CVE-2020-15658 https://bugzilla.redhat.com/show_bug.cgi?id=1861647 • CWE-138: Improper Neutralization of Special Elements CWE-754: Improper Check for Unusual or Exceptional Conditions •

Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. Apache HTTP Server versiones 2.4.20 hasta 2.4.43, cuando trace/debug fue habilitado para el módulo HTTP/2 y en determinados patrones de tráfico de borde, se hicieron declaraciones de registro en la conexión errónea, causando un uso concurrente de grupos de memoria. Configurando el LogLevel de mod_http2 sobre "info" mitigará esta vulnerabilidad para los servidores sin parches A flaw was found in Apache httpd in versions 2.4.20 to 2.4.43. Logging using the wrong pool by mod_http2 at debug/trace log level may lead to potential crashes and denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00068.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00081.html http://packetstormsecurity.com/files/160393/Apache-2-HTTP2-Module-Concurrent-Pool-Usage.html https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2020-11993 https://lists.apache.org/thread.html/r06f0d87ebb6d59ed8379633f36f72f5b1f79cadfda72ede0830b42cf%40%3Ccvs.httpd.apache.org%3E https://lists&# • CWE-400: Uncontrolled Resource Consumption CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
