https://notcve.org/view.php?id=CVE-2020-14361
A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo en X.Org Server versiones anteriores a xorg-x11-server 1.20.9. Un subdesbordamiento de enteros que conlleva a un desbordamiento del búfer de la pila puede conllevar a una vulnerabilidad de escalada de privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=1869142 https://lists.x.org/archives/xorg-announce/2020-August/003058.html https://security.gentoo.org/glsa/202012-01 https://usn.ubuntu.com/4488-2 https://www.zerodayinitiative.com/advisories/ZDI-20-1418 https://access.redhat.com/security/cve/CVE-2020-14361 • CWE-191: Integer Underflow (Wrap or Wraparound) •

CVE-2020-8622 – A truncated TSIG response can lead to an assertion failure
https://notcve.org/view.php?id=CVE-2020-8622
In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and message, and spoof a truncated response to trigger an assertion failure, causing the server to exit. En BIND versiones 9.0.0 -) 9.11.21, 9.12.0 -) 9.16.5, 9.17.0 -) 9.17.3, también afecta a versiones 9.9.3-S1 -) 9.11.21-S1 de BIND 9 Supported Preview Edition, un atacante sobre la ruta de la red para una petición firmada por TSIG, u operando el servidor que recibe la petición firmada por TSIG, podría enviar una respuesta truncada a esa petición, desencadenando un fallo de aserción y causando que el servidor salga. Alternativamente, un atacante fuera de la ruta tendría que adivinar correctamente cuándo fue enviada una petición firmada por TSIG, junto con otras características del paquete y mensaje, y falsificar una respuesta truncada para desencadenar un fallo de aserción, causando la salida del servidor.
