CVE-2020-25219 – libproxy: uncontrolled recursion via an infinite stream response leading to stack exhaustion
https://notcve.org/view.php?id=CVE-2020-25219
09 Sep 2020 — url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion. La función url::recvline en el archivo url.cpp en libproxy versiones 0.4.x hasta 0.4.15, permite a un servidor HTTP remoto activar una recursividad no controlada por medio de una respuesta compuesta por una transmisión infinita que carece de un carácter newline.

CVE-2020-24659 – gnutls: Heap buffer overflow in handshake with no_renegotiation alert sent
https://notcve.org/view.php?id=CVE-2020-24659
04 Sep 2020 — An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.

CVE-2020-14364 – QEMU: usb: out-of-bounds r/w access issue while processing usb packets
https://notcve.org/view.php?id=CVE-2020-14364
31 Aug 2020 — An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.
