An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service. Se encontró un problema de fallo de aserción en el Network Block Device (NBD) en todas las versiones de QEMU anteriores a QEMU versión 5.0.1. Este fallo ocurre cuando un cliente nbd envía una petición que cumple con las especificaciones que está cerca del límite de la longitud máxima permitida de la petición. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00086.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10761 https://security.gentoo.org/glsa/202011-09 https://security.netapp.com/advisory/ntap-20200731-0001 https://usn.ubuntu.com/4467-1 https://www.openwall.com/lists/oss-security/2020/06/09/1 • CWE-617: Reachable Assertion •
CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 1CVE-2020-13974 – kernel: integer overflow in k_ascii() in drivers/tty/vt/keyboard.c
https://notcve.org/view.php?id=CVE-2020-13974
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. NOTA: Los miembros de la comunidad argumentan que el desbordamiento de números enteros no conduce a un problema de seguridad en este caso A flaw integer overflow in the Linux kernel's virtual terminal keyboard driver was found in the way the user sends some specific keyboard code multiple times. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00009.html https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=dad0bf9ce93fa40b667eccd3306783f4db4b932b https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b86dab054059b970111b5516ae548efaae5b3aae https://lists.debian.org/debian-lts-announce/2020/08/msg00019.html https://lkml.org/lkml/2020/3/22/482 https://usn.u • CWE-190: Integer Overflow or Wraparound •
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 •

FFmpeg 2.8 and 4.2.3 has a use-after-free via a crafted EXTINF duration in an m3u8 file because parse_playlist in libavformat/hls.c frees a pointer, and later that pointer is accessed in av_probe_input_format3 in libavformat/format.c. FFmpeg versión 2.8 y versión 4.2.3, presenta un uso de la memoria previamente liberada por medio de una duración EXTINF diseñada en un archivo m3u8 porque la función parse_playlist en la biblioteca libavformat/hls.c libera un puntero, y luego este puntero es accedido en la función av_probe_input_format3 en la biblioteca libavformat/format.c • https://github.com/FFmpeg/FFmpeg/commit/6959358683c7533f586c07a766acc5fe9544d8b2 https://lists.debian.org/debian-lts-announce/2020/07/msg00022.html https://patchwork.ffmpeg.org/project/ffmpeg/patch/20200529033905.41926-1-lq%40chinaffmpeg.org https://security.gentoo.org/glsa/202007-58 https://trac.ffmpeg.org/ticket/8673 https://usn.ubuntu.com/4431-1 https://www.debian.org/security/2020/dsa-4722 • CWE-416: Use After Free •
