In exif_data_load_data_content of exif-data.c, there is a possible UBSAN abort due to an integer overflow. This could lead to remote denial of service with no additional execution privileges needed. User interaction is needed for exploitation.Product: AndroidVersions: Android-10Android ID: A-146428941 En la función exif_data_load_data_content del archivo exif-data.c, se presenta un posible aborto de UBSAN debido a un desbordamiento de enteros.

Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Una limpieza incompleta de operaciones de lectura de un registro especial específico en algunos Intel® Processors puede permitir a un usuario autenticado habilitar potencialmente una divulgación de información por medio de un acceso local A new domain bypass transient execution attack known as Special Register Buffer Data Sampling (SRBDS) has been found. This flaw allows data values from special internal registers to be leaked by an attacker able to execute code on any core of the CPU. An unprivileged, local attacker can use this flaw to infer values returned by affected instructions known to be commonly used during cryptographic operations that rely on uniqueness, secrecy, or both. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00031.html http://www.openwall.com/lists/oss-security/2020/07/14/5 https://cert-portal.siemens.com/productcert/pdf/ssa-534763.pdf https://kc.mcafee.com/corporate/index?page=content&id=SB10318 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message • CWE-459: Incomplete Cleanup •

An issue was discovered in the Linux kernel 4.4 through 5.7.1. drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community argue that the integer overflow does not lead to a security issue in this case. Se detectó un problema en el kernel de Linux versión 4.4 hasta la versión 5.7.1. En el archivo drivers/tty/vt/keyboard.c presenta un desbordamiento de enteros si se llama a la función k_ascii varias veces seguidas, también se conoce como CID-b86dab054059.

CVSS: 6.5EPSS: 0%CPEs: 7EXPL: 2CVE-2020-12049 – dbus: denial of service via file descriptor leak
https://notcve.org/view.php?id=CVE-2020-12049
An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients. Se detectó un problema en dbus versiones posteriores a 1.3.0 e incluyéndola y anteriores a 1.12.18. El DBusServer en libdbus, como es usado en dbus-daemon, filtra los descriptores de archivo cuando un mensaje excede el límite del descriptor de archivo por mensaje. • http://packetstormsecurity.com/files/172840/D-Bus-File-Descriptor-Leak-Denial-Of-Service.html http://www.openwall.com/lists/oss-security/2020/06/04/3 https://gitlab.freedesktop.org/dbus/dbus/-/issues/294 https://gitlab.freedesktop.org/dbus/dbus/-/tags/dbus-1.10.30 https://gitlab.freedesktop.org/dbus/dbus/-/tags/dbus-1.12.18 https://gitlab.freedesktop.org/dbus/dbus/-/tags/dbus-1.13.16 https://security.gentoo.org/glsa/202007-46 https://securitylab.github& • CWE-400: Uncontrolled Resource Consumption CWE-404: Improper Resource Shutdown or Release •
