A Lucky 13 timing side channel in mbedtls_ssl_decrypt_buf in library/ssl_msg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length. Un canal lateral de sincronización Lucky versión 13, en la función mbedtls_ssl_decrypt_buf en el archivo library/ssl_msg.c en Trusted Firmware Mbed TLS versiones hasta 2.23.0, permite a un atacante recuperar información de la clave secreta. Esto afecta al modo CBC debido a una diferencia de tiempo calculada basada en una longitud de relleno • https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5OSOFUD6UTGTDDSQRS62BPXDU52I6PUA https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IRPBHCQKZXHVKOP5O5EWE7P76AWGUXQJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OD3NM6GD73CTFFRBKG5G2ACXGG7QQHCC https://tls.mbed.org/tech-updates/security-advisories https://tls.mbed.org/tech-updates/security-adv • CWE-203: Observable Discrepancy •

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
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. Se encontró un fallo de acceso de lectura/escritura fuera de límites en el emulador USB de QEMU en versiones anteriores a la 5.2.0. Este problema ocurre mientras se procesan paquetes USB de un invitado cuando USBDevice "setup_len" excede su "data_buf [4096]" en las rutinas do_token_in, do_token_out. • https://github.com/gejian-iscas/CVE-2020-14364 https://github.com/y-f00l/CVE-2020-14364 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00024.html https://bugzilla.redhat.com/show_bug.cgi?id=1869201 https://lists.debian.org/debian-lts-announce/2020/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JTZQUQ6ZBPMFMNAUQBVJFELYNMUZLL6P https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M52WIRMZL6T • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVE-2020-14352 – librepo: missing path validation in repomd.xml may lead to directory traversal
https://notcve.org/view.php?id=CVE-2020-14352
A flaw was found in librepo in versions before 1.12.1. A directory traversal vulnerability was found where it failed to sanitize paths in remote repository metadata. An attacker controlling a remote repository may be able to copy files outside of the destination directory on the targeted system via path traversal. This flaw could potentially result in system compromise via the overwriting of critical system files. The highest threat from this flaw is to users that make use of untrusted third-party repositories. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00055.html https://bugzilla.redhat.com/show_bug.cgi?id=1866498 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/33RX4P5R5YL4NZSFSE4NOX37X6YCXAS4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OOMDEQBRJ7SO2QWL7H23G3VV2VSCUYOY https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
