CVSS: 6.6EPSS: 0%CPEs: 15EXPL: 0CVE-2020-14355 – spice: multiple buffer overflow vulnerabilities in QUIC decoding code
https://notcve.org/view.php?id=CVE-2020-14355
Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution. Se encontraron múltiples vulnerabilidades de desbordamiento de búfer en el proceso de decodificación de imágenes QUIC del sistema de visualización remota SPICE, versiones anteriores a spice-0.14.2-1. Tanto el cliente SPICE (spice-gtk) como el servidor están afectados por estos defectos. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00001.html https://bugzilla.redhat.com/show_bug.cgi?id=1868435 https://lists.debian.org/debian-lts-announce/2020/11/msg00001.html https://lists.debian.org/debian-lts-announce/2020/11/msg00002.html https://usn.ubuntu.com/4572-1 https://usn.ubuntu.com/4572-2 https://www.debian.org/security/2020/dsa-4771 https://www.openwall.com/lists/oss • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2020-25641
A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

https://notcve.org/view.php?id=CVE-2020-25643
A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo de corrupción de la memoria en el kernel de Linux en versiones anteriores a 5.9-rc7, en el módulo HDLC_PPP en la manera en que recibe paquetes malformados por el protocolo PPP. Un usuario remoto podría usar este fallo para bloquear el sistema o causar una denegación de servicio A flaw was found in the HDLC_PPP module of the Linux kernel. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00042.html https://bugzilla.redhat.com/show_bug.cgi?id=1879981 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=66d42ed8b25b64eb63111a2b8582c5afc8bf1105 https://lists.debian.org/debian-lts-announce/2020/10/msg00028.html https://lists.debian.org/debian-lts-announce/2020/10/msg00032.html https://lists.debian.org/debian-lts-announce/ • CWE-20: Improper Input Validation •

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 •
