https://notcve.org/view.php?id=CVE-2021-3748
A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process. Se ha encontrado una vulnerabilidad de uso de memoria previamente liberada en el dispositivo virtio-net de QEMU. Podría ocurrir cuando la dirección del descriptor pertenece a la región de acceso no directo, debido a que num_buffers es establecido después de que el elemento virtqueue haya sido desmapeado. • https://bugzilla.redhat.com/show_bug.cgi?id=1998514 https://github.com/qemu/qemu/commit/bedd7e93d01961fcb16a97ae45d93acf357e11f6 https://lists.debian.org/debian-lts-announce/2022/04/msg00002.html https://lists.debian.org/debian-lts-announce/2022/09/msg00008.html https://lists.nongnu.org/archive/html/qemu-devel/2021-09/msg00388.html https://security.gentoo.org/glsa/202208-27 https://security.netapp.com/advisory/ntap-20220425-0004 https://ubuntu.com/security/CVE-2021-3748 https://access. • CWE-416: Use After Free •
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') •

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Networking). Supported versions that are affected are Java SE: 7u241 and 8u231; Java SE Embedded: 8u231. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00060.html https://access.redhat.com/errata/RHSA-2020:0157 https://access.redhat.com/errata/RHSA-2020:0196 https://access.redhat.com/errata/RHSA-2020:0202 https://access.redhat.com/errata/RHSA-2020:0231 https://access.redhat.com/errata/RHSA-2020:0465 https://access.redhat.com/errata/RHSA-2020:0467 https://access.redhat.com/errata/RHSA-2020:0468 https://access.redhat.com/errata/RHSA-2020:0469 https://access. • CWE-770: Allocation of Resources Without Limits or Throttling •
